General Description:

The TC7126A is a 3-1/2 digit CMOS Analog-to-Digital Converter (ADC) containing all the active components necessary to construct a 0.05 resolution measure ment 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.

A low-cost, high resolution indicating meter requires only a display, four resistors, and four capacitors. The TC7126A’s extremely low-power drain and 9V battery operation make it ideal for portable applications.
