General Description
The Maxim ICL7136 is a monolithic analog to digital con-
verter with very high input impedance. On-board active
components include segment drivers, segment decod-
ers, voltage reference and a clock circuit. The ICL7136
directly drives a hon-multiplexed liquid crystal (LCD) dis-
play, requiring no external display drive circuitry. Signiti-
cantly reduced power Consumption makes the ICL7136 a
superior device, especially for portable systems.
Versatility and accuracy are inherent features of this con-
verter. The dual-slope conversion technique automatical-
ly rejects interference signals common in industrial envi-
ronments. The true differential input and reference are
particularly useful when making ratiometric measure-
ments (ohms or bridge transducers). and the zero-inte-
grator phase in Maxim's ICL7136 eliminates overrange
hangover and hysteresis effects. Finally, this device of-
fers high accuracy by lowering rollover error to less than
one count and zero reading drift to less than 1 pNPt1,
Applications
These devices can be used in a wide range of digital
panel meter applications. Most applications, however, in-
voIve the measurement and display of analog data:
