Figure 28 shows a simplified block diagram of the REF50xx. OUTPUT ADJUSTMENT USING THE TRIM/NR PIN VIN REF50xx R2 The REF50xx provides a very accurate, factory-trimmed voltage output. However, VOUT can be adjusted using the trim and noise reduction pin (TRIM/NR, pin 5).

REF50xx Simplified Block Diagram BASIC CONNECTIONS Figure 29 shows the typical connections for the REF50xx. A supply bypass capacitor ranging between 1mF to 10mF is recommended. A 1mF to 50mF output capacitor (CL) must be connected from VOUT to GND. The ESR value of CL must be less than or equal to 1.5 to ensure output stability. To minimize noise, the recommended ESR of CL is between 1 and 1.5. +VSUPPLY REF50xx DNC CBYPASS 1mF to 10mF VIN TEMP DNC Figure 30. VOUT Adjustment Using the TRIM/NR Pin The REF50xx allows access to the bandgap through the TRIM/NR pin. Placing a capacitor from the TRIM/NR pin to GND (see Figure 31) in combination with the internal R3 and R4 resistors creates a low-pass filter. A capacitance of 1mF creates a low-pass filter with the corner frequency between 10Hz and 20Hz. Such a filter decreases the overall noise measured on the VOUT pin by half. Higher capacitance results in a lower filter cutoff frequency, further reducing output noise. Note that use of this capacitor increases startup time.

The drift is calculated using the box method, as described by the following equation: V OUTMAX * V OUTMIN Drift + V OUT Temp Range To avoid errors caused by low-impedance loading, buffer the TEMP pin output with a suitable low-temperature drift op amp, such as the OPA333, OPA335, or OPA376, as shown in Figure 32. +V 106(ppm) (1) The REF50xx features a maximum drift coefficient of 3ppm/C for the high-grade version, and 8ppm/C for the standard-grade.

Thermal hysteresis for the REF50xx is defined as the change in output voltage after operating the device at +25C, cycling the device through the specified temperature range, and returning to +25C. It can be expressed as Equation 2: VHYST = ( ( |VPRE - VPOST| * 106(ppm) VNOM (2) Where: VHYST = thermal hysteresis (in units of ppm). VNOM = the specified output voltage. VPRE = output voltage measured at +25C pretemperature cycling. VPOST = output voltage measured after the device has been cycled from +25C through the specified temperature range of -40C to +125C and returned to +25C. Figure 32. Buffering the TEMP Pin Output POWER DISSIPATION The REF50xx family is specified to deliver current loads of 10mA over the specified input voltage range. The temperature of the device increases according to the equation: TJ = TA + PD x qJA (3) Where: TJ = Junction temperature (C) TA = Ambient temperature (C) PD = Power dissipated (W) qJA = Junction-to-ambient thermal resistance (C/W) The REF50xx junction temperature must not exceed the absolute maximum rating of +150C. TEMPERATURE MONITORING NOISE PERFORMANCE The temperature output terminal (TEMP, pin 3) provides a temperature-dependent voltage output with approximately 60k source impedance. As seen in Figure 8, the output voltage follows the nominal relationship: Typical 0.1Hz to 10Hz voltage noise for each member of the REF50xx family is specified in the Electrical Characteristics: Per Device table. The noise voltage increases with output voltage and operating temperature. Additional filtering can be used to improve output noise levels, although care should be taken to ensure the output impedance does not degrade performance. VTEMP PIN = 509mV + 2.64 x T(C) This pin indicates general chip temperature, accurate to approximately 15C. Although it is not generally suitable for accurate temperature measurements, it can be used to indicate temperature changes or for temperature compensation of analog circuitry. A temperature change of 30C corresponds to an approximate 79mV change in voltage at the TEMP pin. The TEMP pin has high output impedance (see Figure 28). Loading this pin with a low-impedance circuit induces a measurement error; however, it does not have any effect on VOUT accuracy.

Figure 33 shows the REF5025 used to provide a 2.5V supply reference voltage. The low drift performance of the REF50xx complements the low offset voltage and zero drift of the OPA735 to provide an accurate solution for split-supply applications. Care must be taken to match the temperature coefficients of R1 and R2. Data acquisition systems often require stable voltage references to maintain accuracy. The REF50xx family features low noise, very low drift, and high initial accuracy for high-performance data converters.

changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as "components") are sold subject to TI's terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI's terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers' products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers' products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI's goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or "enhanced plastic" are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such components to meet such requirements.
