LPC662

Low Power CMOS Dual Operational Amplifier

General Description

The LPC662 CMOS Dual operational amplifier is ideal for

operation from a single supply. It features a wide range of

operating voltage from +5V to +15V, rail-to-rail output swing

in addition to 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. In-

put V

OS, drift, and broadband noise as well as voltage gain

(into 100 k

Ω and5kΩ) are all equal to or better than widely

accepted bipolar equivalents, while the power supply re-

quirement is typically less than 0.5 mW.

This chip is built with National’s advanced Double-Poly

Silicon-Gate CMOS process.

See the LPC660 datasheet for a Quad CMOS operational

amplifier and LPC661 for a single CMOS operational ampli-

fier with these same features.
