LPC660
Low Power CMOS Quad Operational Amplifier
General 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 V
OS
, drift, and broadband noise as well as
voltage gain (into 100 k鈩?and 5 k鈩? 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鈥檚 advanced Double-Poly
Silicon-Gate CMOS process.
See the LPC662 datasheet for a Dual CMOS operational
amplifier and LPC661 datasheet for a single CMOS opera-
tional amplifier with these same features.
