PRELIMINARY INFORMATION

TC1027

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 indepen-

dent of the magnitude of the power supply voltage. The

TC1027 is optimized for low supply voltage and very low

supply current operation (15

µA max) making it ideal for

battery operated applications.

Packaged in a 16-pin QSOP, SOIC (0.150 wide) or 16-

pin DIP, the TC1027 is ideal for applications requiring high

integration, small size and low power.
