General Description
The TC1025 is a dual low-power comparator with a
typical supply current of 8μA and operation ensured to
VDD = 1.8V. Input and output signal swing is rail-to-rail.
Available in a space-saving 8-pin MSOP package, the
TC1025 consumes half the board area required by a
standard 8-Pin SOIC package. It is also available in
8-Pin SOIC and PDIP packages. It is ideal for applica-
tions requiring high integration, small-size and low
power.
