Overview
ICL7129 August 1997 41/2 Digit LCD, Single-Chip A/D Converter Description The Intersil ICL7129 is a very high performance 41/2-digit, analog-to-digital converter that directly drives a multiplexed liquid crystal display.
This single chip CMOS integrated circuit requires only a few passive components and a reference to operate.
It is ideal for high resolution hand-held digital multimeter applications.
The performance of the ICL7129 has not been equaled before in a single chip A/D converter.
The successive integration technique used in the ICL7129 results in accuracy better than 0.
005% of full scale and resolution down to 10µV/count.
The ICL7129, drawing only 1mA from a 9V battery, is well suited for battery powered instruments.
Provision has been made for the detection and indication of a “LOW/BATTERY” condition.
Autoranging instruments can be made with the ICL7129 which provides overrange and underrange outputs and 10:1 range changing input.
The ICL7129 instantly checks for continuity...
