Description

ADC 4-1/2 DIGIT LCD DRIVER 40DIP
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 10 μV per count. 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. Overrange and underrange outputs, along with 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.
