LMC6442 www.ti.com SNOS013E - SEPTEMBER 1997 - REVISED MARCH 2013 LMC6442 Dual Micropower Rail-to-Rail Output Single Supply Operational Amplifier Check for Samples: LMC6442 FEATURES DESCRIPTION * * * * * * * * * The LMC6442 is ideal for battery powered systems, where very low supply current (less than one microamp per amplifier) and Rail-to-Rail output swing is required. It is characterized for 2.2V to 10V operation, and at 2.2V supply, the LMC6442 is ideal for single (Li-Ion) or two cell (NiCad or alkaline) battery systems. 1 2 (Typical, VS = 2.2V) Output Swing to Within 30 mV of Supply Rail High Voltage Gain 103 dB Gain Bandwidth Product 9.5 KHz Ensured for: 2.2V, 5V, 10V Low Supply Current 0.95 A/Amplifier Input Voltage Range -0.3V to V+ -0.9V 2.1 W/Amplifier Power Consumption Stable for AV +2 or AV -1 Operation from single supply is enhanced by the wide common mode input voltage range which includes the ground (or negative supply) for ground sensing applications. Very low (5 fA, typical) input bias current and near constant supply current over supply voltage enhance the LMC6442's performance near the endof-life battery voltage. APPLICATIONS * * * * * * * * The LMC6442 is designed for battery powered systems that require long service life through low supply current, such as smoke and gas detectors, and pager or personal communications systems. Portable Instruments Smoke/Gas/CO/Fire Detectors Pagers/Cell Phones Instrumentation Thermostats Occupancy Sensors Cameras Active Badges Designed for closed loop gains of greater than plus two (or minus one), the amplifier has typically 9.5 KHz GBWP (Gain Bandwidth Product). Unity gain can be used with a simple compensation circuit, which also allows capacitive loads of up to 300 pF to be driven, as described in the Application Information section.

However, it is also possible to operate the device in a unity gain configuration by adding external compensation as shown in Figure 35: Figure 35. AV = +1 Operation by adding CC and RC Using this compensation technique it is possible to drive capacitive loads of up to 300 pF without causing oscillations (see the Typical Performance Characteristics for step response plots). This compensation can also be used with other gain settings in order to improve stability, especially when driving capacitive loads (for optimum performance, RC and CC may need to be adjusted). USING "T" NETWORK Compromises need to be made whenever high gain inverting stages need to achieve a high input impedance as well. This is especially important in low current applications which tend to deal with high resistance values. Using a traditional inverting amplifier, gain is inversely proportional to the resistor value tied between the inverting terminal and input while the input impedance is equal to this value. For example, in order to build an inverting amplifier with an input impedance of 10M and a gain of 100, one needs to come up with a feedback resistor of 1000 M -an expensive task. An alternate solution is to use a "T" Network in the feedback path, as shown in Figure 36. Closed loop gain, AV is given by: (1) Figure 36. "T" Network Used to Replace High Value Resistor It must be noted, however, that using this scheme, the realizable bandwidth would be less than the theoretical maximum. With feedback factor, , defined as: (2) (3) BW(-3 dB) GBWP * In this case, assuming a GBWP of about 10 KHz, the expected BW would be around 50 Hz (vs. 100 Hz with the conventional inverting amplifier). 12 Submit Documentation Feedback Copyright (c) 1997-2013, Texas Instruments Incorporated Product Folder Links: LMC6442 LMC6442 www.ti.com SNOS013E - SEPTEMBER 1997 - REVISED MARCH 2013 Looking at the problem from a different view, with RF defined by AV*Rin, one could select a value for R in the "T" Network and then determine R1 based on this selection: (4) Figure 37. "T" Network Values for Various Values of R For convenience, Figure 37 shows R1 vs. RF for different values of R. DESIGN CONSIDERATIONS FOR CAPACITIVE LOADS As with many other opamps, the LMC6442 is more stable at higher closed loop gains when driving a capacitive load. Figure 38 shows minimum closed loop gain versus load capacitance, to achieve less than 10% overshoot in the output small signal response. In addition, the LMC6442 is more stable when it provides more output current to the load and when its output voltage does not swing close to V-. The LMC6442 is more tolerant to capacitive loads when the equivalent output load resistance is lowered or when output voltage is 1V or greater from the V- supply. The capacitive load drive capability is also improved by adding an isolating resistor in series with the load and the output of the device. Figure 39 shows the value of this resistor for various capacitive loads (AV = -1), while limiting the output to less than 10 % overshoot. Referring to the Typical Performance Characteristics plot of Phase Margin (Worst Case) vs. Supply Voltage, note that Phase Margin increases as the equivalent output load resistance is lowered. This plot shows the expected Phase Margin when the device output is very close to V-, which is the least stable condition of operation. Comparing this Phase Margin value to the one read off the Open Loop Gain/Phase vs. Frequency plot, one can predict the improvement in Phase Margin if the output does not swing close to V-. This dependence of Phase Margin on output voltage is minimized as long as the output load, RL, is about 1M or less. Output Phase Reversal: The LMC6442 is immune against this behavior even when the input voltages exceed the common mode voltage range. Output Time Delay: Due to the ultra low power consumption of the device, there could be as long as 2.5 ms of time delay from when power is applied to when the device output reaches its final value.
