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 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 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.

For good CMRR over temperature, low drift resistors should be used. Matching of R3 to R6 and R4 to R7 affects CMRR. Gain may be adjusted through R2.
CMRR may be adjusted through R7.
