TC7126A Overview
The TC7126A is a 3-1/2 digit CMOS Analog-to-Digital Converter (ADC) containing all the active ponents necessary to construct a 0.05% resolution measurement system. Seven-segment decoders, digit and polarity drivers, voltage reference, and clock circuit are integrated on-chip. The TC7126A directly drives a Liquid Crystal Display (LCD), and includes a backplane driver.
