LMC6582 Dual/LMC6584 Quad
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.
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.
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.
