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.
3 ^{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
4 ^{supply current operation (15µA 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.
