DESCRIPTION

The LPC660 CMOS Quad operational amplifier is

ideal for operation from a single supply. It features a

wide range of operating voltages from +5V to +15V

and features 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. 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 power supply requirement is typically less

than 1 mW.

This chip is built with National's advanced Double-

Poly Silicon-Gate CMOS process.

See the LPC662 datasheet for a Dual CMOS

operational amplifier and LPC661 datasheet for a

single CMOS operational amplifier with these same

features.
