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
operates from two 1.5V alkaline cells down to V_DD =
1.8V. Supply current is only typically 12µA, 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.
