41/2 Digit Lcd, Single-chip A/d Converter CorporationThe 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 cir-
cuit 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 integra-
tion technique used in the ICL7129 results in accuracy better
than 0.005% of full scale and resolution down to 10V/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, giving both a visual indication and a Logic level
output which CAN enable an external audible transducer. These
features and the high performance of the ICL7129 make it an
extremely versatile and accurate instrument-on-a-chip. By Intersil Corporation
