LMC6061

LMC6061 Precision CMOS Single Micropower Operational Amplifier November 1994 LMC6061 Precision CMOS Single Micropower Operational Amplifier General Description The LMC6061 is a precision single low offset voltage, micropower operational amplifier, capable of precision single supply operation. Performance characteristics include ultra low input bias current, high voltage gain, rail-to-rail output swing, and an input common mode voltage range that includes ground. These features, plus its low power consumption, make the LMC6061 ideally suited for battery powered applications. Other applications using the LMC6061 include precision full-wave rectifiers, integrators, references, sample-and-hold circuits, and true instrumentation amplifiers. This device is built with National’s advanced double-Poly Silicon-Gate CMOS process. For designs that require higher speed, see the LMC6081 precision single operational amplifier. For a dual or quad operational amplifier with similar features, see the LMC6062 or LMC6064 respectively.
