GENERAL DESCRIPTION
The TC1031 is a low power, complimentary output
comparator plus voltage reference designed specifically for
low power applications.
The TC1031 is designed for operation from a single
supply, however, operation from dual supplies is also possible, and the power supply current drain is independent of
the magnitude of the power supply voltage. Maximum
supply current is 6µA and operation is guaranteed to VDD =
1.8V. The input common mode range includes ground and
the output swing is rail-to-rail.
Packaged in a space-saving SOT23A-5*, the TC1031 is
ideal for applications requiring high integration, small size
and low power.
