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.

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, V_S3V and R_L10 kΩ)

n CMRR and PSRR: 82 dB

n Ultra Low Input Current:

80 fA

n High Voltage Gain (V_S3V, R_L10 kΩ): 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.
