Description

The LMC662 CMOS Dual operational amplifier is ideal for operation from a single supply. It operates 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 realistic loads (2 k and 600) are all equal to or better than widely accepted bipolar equivalents.

This chip is built with National's advanced Double-Poly Silicon-Gate CMOS process.

See the LMC660 datasheet for a Quad CMOS operational amplifier with these same features.

Applications
•High-impedance buffer or preamplifier
•Precision current-to-voltage converter
•Long-term integrator
•Sample-and-hold circuit
•Peak detector
•Medical instrumentation
•Industrial controls
•Automotive sensors

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
