General Description
The TC820 is a 3-3/4 digit, multi-measurement system
especially suited for use in portable instruments. It inte-
grates a dual slope A/D converter, auto-ranging fre-
quency counter and logic probe into a single 44-pin
surface mount, or 40-pin through hole package. The
TC820 operates from a single 9V input voltage (bat-
tery) and features a built-in battery low flag. Function
and decimal point selection are accomplished with sim-
ple logic inputs designed for direct connection to an
external microcontroller or rotary switch.
