TC815CBU

3-1/2 Digit Auto-Ranging A/D Converter with Triplex LCD Drive and Display Hold Function

Microchip Technology 

TC815

A continuity buzzer output is activated with inputs less

than 1% of full scale. An overrange input signal also

enables the buzzer, except during resistance measure-

ments, and flashes the MSD display.

Featuring single 9V battery operation, 10mW power

consumption, a precision internal voltage reference

(75ppm/°C max TC) and a compact surface mounted

64-pin quad flat package, the TC815 is ideal for porta-

ble instruments.
