LMC6494 - CMOS Rail-to-Rail Input and Output Operational Amplifier

General Description

The LMC6492/LMC6494 amplifiers were specifically developed for single supply applications that operate from

40˚C to +125˚C.

This feature is well-suited for automotive systems because of the wide temperature range.

LMC6492 Dual/LMC6494 Quad CMOS Rail-to-Rail Input and Output Operational Amplifier October 1994 LMC6492 Dual/LMC6494 Quad CMOS Rail-to-Rail Input and Output Operational Amplifier General Description The LMC6492/LMC6494 amplifiers were specifically developed for single supply applications that operate from −40˚C to +125˚C. This feature is well-suited for automotive systems because of the wide temperature range. A unique design topology enables the LMC6492/LMC6494 common-mode voltage range to accommodate input signals beyond the rails. This eliminates non-linear output errors due to input signals exceeding a traditionally limited common-mode voltage range. The LMC6492/LMC6494 signal range has a high CMRR of 82 dB for excellent accuracy in non-inverting circuit configurations.
