Overview

LPC661 Low Power CMOS Operational Amplifier May 1998 LPC661 Low Power CMOS Operational Amplifier General Description The LPC661 CMOS operational amplifier is ideal for operation from a single supply.
It features a wide range of operating supply voltage from +5V to +15V, rail-to-rail output swing and an input common-mode range that includes ground.
Performance limitations that have plagued CMOS amplifiers in the past are not a problem with this design.
Input VOS, drift, and broadband noise as well as voltage gain (into 100 kΩ and 5 kΩ) are all equal to or better than widely accepted bipolar equivalents, while the supply current requirement is typically 55 µA.
This chip is built with National’s advanced Double-Poly Silicon-Gate CMOS process.
See the LPC660 datasheet for a Quad CMOS operational amplifier or the LPC662 data sheet for a Dual CMOS operational amplifier with these same features.
