ADS7809 7809 ADS SBAS017C - NOVEMBER 1996 - REVISED OCTOBER 2006 16-Bit 10s Serial CMOS Sampling ANALOG-TO-DIGITAL CONVERTER FEATURES DESCRIPTION 100kHz SAMPLING RATE 86dB SINAD WITH 20kHz INPUT 2LSB INL DNL: 16 Bits No Missing Codes SIX SPECIFIED INPUT RANGES SERIAL OUTPUT SINGLE +5V SUPPLY OPERATION PIN-COMPATIBLE WITH 12-BIT ADS7808 USES INTERNAL OR EXTERNAL REFERENCE 100mW MAX POWER DISSIPATION 0.3" SO-20 SIMPLE DSP INTERFACE The ADS7809 is a complete 16-bit sampling Analog-toDigital (A/D) converter using state-of-the-art CMOS structures. It contains a 16-bit capacitor-based Successive Approximation Register (SAR) A/D converter with sample-andhold, reference, clock, and a serial data interface. Data can be outputted using the internal clock, or can be synchronized to an external data clock. The ADS7809 also provides an output synchronization pulse for ease of use with standard DSP processors. The ADS7809 is specified at a 100kHz sampling rate, and specified over the full temperature range. Laser-trimmed scaling resistors provide various input ranges including 10V and 0V to 5V, while an innovative design operates from a single +5V supply, with power dissipation under 100mW. The ADS7809 is available in a 0.3" SO-20, and is fully specified for operation over the industrial -40C to +85C range.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. NOTE: (1) Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to absolute maximum conditions for extended periods may affect device reliability.

(3) As measured with fixed resistors shown in Figure 4. Adjustable to zero with external potentiometer. (4) For bipolar input ranges, full-scale error is the worst case of -Full Scale or +Full Scale untrimmed deviation from ideal first and last code transitions, divided by the transition voltage (not divided by the full-scale range) and includes the effect of offset error. For unipolar input ranges, full-scale error is the deviation of the last code transition divided by the transition voltage. It also includes the effect of offset error.

See Table I and Figure 4 for input range connections. Analog Ground. Used internally as ground reference point. Minimal current flow. Analog Input. See Table I and Figure 4 for input range connections. 4 R3IN Analog Input. See Table I and Figure 4 for input range connections. 5 CAP Reference Buffer Capacitor. 2.2F Tantalum to ground. 6 REF Reference Input/Output. Outputs internal 2.5V reference. Can also be driven by external system reference. In both cases, bypass to ground with a 2.2F Tantalum capacitor. 7 AGND2 Analog Ground 8 SB/BTC Select Straight Binary or Binary Two's Complement data output format. If HIGH, data will be output in a Straight Binary format. If LOW, data will be output in a Binary Two's Complement format. 9 EXT/INT Select External or Internal Clock for transmitting data. If HIGH, data will be output synchronized to the clock input on DATACLK. If LOW, a convert command will initiate the transmission of the data from the previous conversion, along with 16 clock pulses output on DATACLK. 10 DGND Digital Ground 11 SYNC Synch Output. If EXT/INT is HIGH, either a rising edge on R/C with CS LOW or a falling edge on CS with R/C HIGH will output a pulse on SYNC synchronized to the external DATACLK. 12 DATACLK 13 DATA 14 TAG Tag Input for use in external clock mode. If EXT/INT is HIGH, digital data input on TAG will be output on DATA with a delay of 16 DATACLK pulses as long as CS is LOW and R/C is HIGH. See Figure 3. 15 R/C Read/Convert Input. With CS LOW, a falling edge on R/C puts the internal sample-and-hold into the hold state and starts a conversion. When EXT/INT is LOW, this also initiates the transmission of the data results from the previous conversion. If EXT/INT is HIGH, a rising edge on R/C with CS LOW, or a falling edge on CS with R/C HIGH, transmits a pulse on SYNC and initiates the transmission of data from the previous conversion. Either an input or an output depending on the EXT/INT level. Output data will be synchronized to this clock. If EXT/INT is LOW, DATACLK will transmit 16 pulses after each conversion, and then remain LOW between conversions. Serial Data Output. Data will be synchronized to DATACLK, with the format determined by the level of SB/BTC. In the external clock mode, after 16 bits of data, the ADS7809 will output the level input on TAG as long as CS is LOW and R/C is HIGH (see Figure 3). If EXT/INT is LOW, data will be valid on both the rising and falling edges of DATACLK, and between conversions DATA will stay at the level of the TAG input when the conversion was started. 16 CS 17 BUSY Busy Output. Falls when a conversion is started, and remains LOW until the conversion is completed and the data is latched into the output shift register. CS or R/C must be HIGH when BUSY rises, or another conversion will start without time for signal acquisition. Chip Select. Internally OR'ed with R/C. 18 PWRD Power Down Input. If HIGH, conversions are inhibited and power consumption is significantly reduced. Results from the previous conversion are maintained in the output shift register. 19 VANA Analog Supply Input. Nominally +5V. Connect directly to pin 20, and decouple to ground with 0.1F ceramic and 10F tantalum capacitors. 20 VDIG Digital Supply Input. Nominally +5V. Connect directly to pin 19. Must be VANA.

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.
