Product Description

GENERAL DESCRIPTION
The TC7126A is a 3-1/2 digit CMOS analog-to-digital
converter (ADC) containing all the active components nec
essary to construct a 0.05% resolution measurement sys
tem. 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.
