Device Overview

Summary

The TC7107 3½ digit LED direct-display drive analog-to-digital converter has a reference with an 80ppm/°C max temperature coefficient. TC7107 based systems may be upgraded without changing external passive component values to the TC7107A for a more precise system. The TC7107 drives common anode light emitting diode (LED) displays directly with 8mA per segment. A low-cost, high-resolution indicating meter requires only a display, four resistors, and four capacitors. High impedance differential inputs offer 1pA leakage current and a 1012 Ohm input impedance. The differential reference input allows ratiometric measurements for ohms or bridge transducer measurements. The 15µVp-p noise performance guarantees a great reading. The auto-zero cycle guarantees a zero display reading with a zero-volts input.
