LMC6462 Dual/LMC6464 Quad

Micropower, Rail-to-Rail Input and Output CMOS

Operational Amplifier

General Description

The LMC6462/4 is a micropower version of the popular

LMC6482/4, combining Rail-to-Rail Input and Output Range

with very low power consumption.

Features

(Typical unless otherwise noted)

n Ultra Low Supply Current 20 µA/Amplifier

n Guaranteed Characteristics at 3V and 5V

The LMC6462/4 provides an input common-mode voltage

range that exceeds both rails. The rail-to-rail output swing of

the amplifier, guaranteed for loads down to 25 kΩ, assures

maximum dynamic sigal range. This rail-to-rail performance

of the amplifier, combined with its high voltage gain makes it

unique among rail-to-rail amplifiers. The LMC6462/4 is an

excellent upgrade for circuits using limited common-mode

range amplifiers.

n Rail-to-Rail Input Common-Mode Voltage Range

n Rail-to-Rail Output Swing

(within 10 mV of rail, V_S5V and R_L25 kΩ)

n Low Input Current 150 fA

n Low Input Offset Voltage 0.25 mV

Applications

n Battery Operated Circuits

n Transducer Interface Circuits

n Portable Communication Devices

n Medical Applications

The LMC6462/4, with guaranteed specifications at 3V and

5V, is especially well-suited for low voltage applications. A

quiescent power consumption of 60 µW per amplifier (at V_S

3V) can extend the useful life of battery operated systems.

The amplifier’s 150 fA input current, low offset voltage of

0.25 mV, and 85 dB CMRR maintain accuracy in

battery-powered systems.
