General Description
The TC1027 is a mixed-function device combining four
general purpose comparators and a voltage reference
in a single 16-pin package. This increased integration
allows the user to replace two packages, which saves
space, lowers supply current, and increases system
performance.
The TC1027 is optimized for low supply voltage and
very low supply current operation (18µA typ), making it
ideal for battery-operated applications. The compara-
tors have rail-to-rail inputs and outputs which allows
operation from low supply voltages with large input and
output signal swings.
Packaged in a 16-Pin QSOP, 16-Pin SOIC (0.150 wide)
or 16-Pin PDIP, the TC1027 is ideal for applications
requiring high integration, small size and low power.
