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 VDD = 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 PDIP, the TC1029 is ideal for battery-operated applications.
