GENERAL DESCRIPTION
The TC1026 is a mixed-function device combining a
general purpose opamp, comparator and voltage reference
in a single 8-pin package.
This increased integration allows the user to replace
two or three packages, saving space, lowering supply
current, and increasing system performance.
The TC1026 is designed specifically for operation from
a single supply, however, operation from dual supplies is
also possible, and the power supply current drain is inde-
pendent of the magnitude of the power supply voltage. The
TC1026 is optimized for low voltage (V
DD
= 1.8V), low
supply current (10碌A(chǔ) max) operation.
Packaged in a space-saving 8-pin MSOP, the TC1026
consumes half the board area of an 8-pin SOIC and
is ideal for applications requiring high integration, small size
and low power.
