DESCRIPTION
AA6081
Precision CMOS Single Operational Amplifier
The AA6081 is a precision low offset voltage operational amplifier, capable of 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 offset voltage, make the AA6081 ideally
suitable for precision circuit applications. The IC is available in
8-pin TSSOP
(AA6081A) and
8-pin SOP
(AA6081S) package. For a dual operational amplifier with
similar features, see the AA6082 respectively.
