... CMOS amplifiers. The LMC6582 excellent choice for circuits where the input common-mode voltage range is a concern. The LMC6582/4 has been designed specifically to improve system performance in low voltage applications. Guaranteed operation down to 1.8V means that this family of amplifiers can operate at the end of discharge (EOD) voltages of sev- eral popular batteries. The amplifier’ ...

... Low Voltage Operation The LMC6582/4 operates at supply voltages of 2.2V and 1.8V. These voltages represent the End of Discharge volt- ages of several popular batteries. The amplifier can operate from 1 Lead-Acid or Lithium Ion battery, or 2NiMH, NiCd, or Carbon-Zinc batteries ...

... No Output Phase Inversion V S 4.0 Capacitive Load Tolerance The LMC6582/4 can typically drive a 100 pF load with V 10V at unity gain without oscillating. The unity gain follower is the most sensitive configuration to capacitive load. Direct capacitive loading reduces the phase margin of op-amps. The combination of the op-amp’s output impedance and the capacitive load induces phase lag ...

... It is generally recognized that any circuit which must operate with less than 1000 pA of leakage current requires special layout of the PC board. When one wishes to take advantage of the ultra-low input current of the LMC6582/4, typically 80 fA essential to have an excellent layout. Fortunately, the techniques of obtaining low leakages are quite simple. First, ...

... The input current of the amplifier causes a slow discharge of the capacitor. This phenomenon is called “drooping”. The LMC6582/4 has a typical input current of 80 fA. This would cause the capacitor to droop at a rate of dv/ 100 pF = 0.8 mV/s. Accuracy in the amplitude measurement is also maintained by an offset voltage of 0.5 mV, and an open-loop gain of 120 dB ...

... This implies a reduction in cost, and a sav- ings of space and power. This is an illustration of a conceptual use of the LMC6582/4. The selectivity of the filter can be improved by increasing the order (number of poles) of the design. ...

... At 3V, the LMC6582/4 can accept a signal up to 300 mV below ground. The common-mode voltage range of the LMC6582/4, which extends beyond both rails is thus a very useful feature in this application. DS012041-34 A typical offset voltage of 0.5 mV, and CMRR main- tain accuracy in the circuit outputs while the rail-to-rail output performance allows for a maximum signal range ...
