TC7129

4-1/2 Digit Analog-to-Digital Converters with

On-Chip LCD Drivers

Features

General Description

• Count Resolution: ±19,999

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, low

power CMOS, the TC7129 ADC is designed specifi-

cally for high resolution, battery powered digital multi-

meter applications. The traditional dual slope method

of A/D conversion has been enhanced with a succes-

sive integration technique to produce readings accu-

rate to better than 0.005% of full scale, and resolution

down to 10µV per count.

• Resolution on 200mV Scale: 10µV

• True Differential Input and Reference

• Low Power Consumption: 500µA at 9V

• Direct LCD Driver for 4-1/2 Digits, Decimal Points,

Low Battery Indicator, and Continuity Indicator

• Over Range and Under Range Outputs

• Range Select Input: 10:1

• High Common Mode Rejection Ratio: 110dB

• External Phase Compensation Not Required

The TC7129 includes features important to multimeter

applications. It detects and indicates low battery condi-

tion. A continuity output drives an annunciator on the

display, and can be used with an external driver to

sound an audible alarm. Over range and under range

outputs and a range change input provide the ability to

create auto-ranging instruments. For snapshot read-

ings, the TC7129 includes a latch-and-hold input to

freeze the present reading. This combination of features

makes the TC7129 the ideal choice for full featured

multimeter and digital measurement applications.
