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
µ
A 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.
