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 frequency 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 (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. Ease of use,low power operation and high functional integration make the TC820 desirable in a variety of analog measurement applications.
