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