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 (18

µAtyp), 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.
