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.
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 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
amplifier with these same features. Applications
n High-impedance buffer
n Precision current-to-voltage converter n Long-term integrator
High-impedance preamplifier
Active filter
