1 / 6 page 1 TC43 LINEAR BUILDING BLOCK – VOLTAGE REFERENCE, DUAL OP AMP, DUAL COMPARATOR WITH SHUTDOWN MODE PRELIMINARY INFORMATION GENERAL DESCRIPTION The TC43 is a mixed-function device combining two general purpose op amps, two general purpose compara- tors and a voltage reference in a single 16-pin package. This increased integration allows the user to replace two or three packages, saving space, lowering supply current, and increasing system performance. A Shutdown input, SHDN, disables the op amps and one of the compara- tors, placing their outputs in a high-impedance state. The reference and one comparator stay active in Shutdown Mode. Standby power consumption is typically 5 µA. The TC43 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. Packaged in a 16-pin narrow SOIC (0.150 wide) or 16-pin DIP, the TC43 is ideal for applications requiring high integration, small size and low power.
