TC7129 Overview
The TC7129 is a 4-1/2 digit Analog-to-Digital Converter (ADC) that directly drives a multiplexed Liquid Crystal Display (LCD). Fabricated in high-performance, lowpower CMOS, the TC7129 ADC is designed specifically for high-resolution, battery-powered digital multimeter applications. The traditional dual-slope method of A/D conversion has been enhanced with a successive integration technique to produce readings...
