General Description
The TC1026 is a mixed-function device combining a
general-purpose op amp, comparator and voltage
reference in a single 8-pin package. This increased
integration allows the user to replace two or three
packages, which saves space, lowers supply current
and increases system performance.
Both the op amp and comparator have rail-to-rail inputs
and outputs which allows operation from low supply
voltages with large input and output swings. The
TC1026 is optimized for low voltage (V_DD = 1.8V), low
supply current (12µA typ) 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. It is also available in 8-Pin SOIC
and 8-Pin PDIP packages.
