LPC661
Low Power CMOS Operational Amplifier
General Description
The LPC661 CMOS operational amplifier is ideal for opera-
tion from a single supply. It features a wide range of operat-
ing 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 V_OS,
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 opera-
tional amplifier with these same features.
