Low Voltage, Rail-To-Rail Input and Output CMOS  
Operational Amplifier  
General Description  
The LMC6582/4 is a high performance operational amplifier  
which can operate over a wide range of supply voltages with  
guaranteed specifications at 1.8V, 2.2V, 3V, 5V, and 10V.  
Features  
(Typical unless otherwise noted)  
n Guaranteed Specs at 1.8V, 2.2V, 3V, 5V, 10V  
n Rail-to-Rail Input Common-Mode Voltage Range  
The LMC6582/4 provides an input common-mode voltage  
range that exceeds both supplies. The rail-to-rail output  
swing of the amplifier assures maximum dynamic signal  
range. This rail-to-rail performance of the amplifier, com-  
bined with its high open-loop voltage gain makes it unique  
among rail-to-rail CMOS amplifiers. The LMC6582/4 is an  
excellent choice for circuits where the input common-mode  
voltage range is a concern.  
n Rail-to-Rail Output Swing  
(within 10 mV of supply rail, VS 3V and RL 10 k)  
n CMRR and PSRR: 82 dB  
n Ultra Low Input Current:

n High Voltage Gain (VS 3V, RL 10 k): 120 dB  
n Unity Gain Bandwidth: 1.2 MHz  
Applications  
n Battery Operated Systems  
n Sensor Amplifiers  
n Portable Communication Devices  
n Medical Instrumentation  
n Level Detectors, Sample-and-Hold Circuits  
n Battery Monitoring  
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’s 80 fA input current, 0.5  
mV offset voltage, and 82 dB CMRR maintain accuracy in  
battery-powered systems.  
For a single, dual or quad CMOS amplifier with similar specs  
and  
a powerdown mode, refer to the LMC6681/2/4  
datasheet.
