General Description

The TC1029 is a dual, CMOS operational amplifier

designed for low-power applications. It is designed

specifically for operation from a single supply, however,

operation from dual supplies is also possible, and the

power supply current drain is independent of the

magnitude of the power supply voltage. The TC1029

1.8V. Supply current is only typically 12

µA, which

significantly extends battery life.

Rail-to-rail inputs and outputs allow operation from low

supply voltages while accommodating large input

signals, yielding larger output signals.

Packaged in an 8-Pin MSOP, SOIC or DIP, the TC1029

is ideal for battery operated applications.
