GENERAL DESCRIPTION
The TC1027 is a mixed-function device combining four
general purpose, complimentary output comparators and a
voltage reference in a single 16-pin package.
This increased integration allows the user to replace
two packages, saving space, lowering supply current, and
increasing system performance.
The TC1027 is designed specifically for operation from
a single supply; however, operation from dual supplies is
also possible. The power supply current drain is independent of the magnitude of the power supply voltage. The
TC1027 is optimized for low supply voltage and very low
supply current operation (15µA max) making it ideal for
battery operated applications.
Packaged in a 16-pin QSOP, SOIC (0.150 wide) or 16pin DIP, the TC1027 is ideal for applications requiring high
integration, small size and low power.
