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.
