ICL7136 FN3086
Rev 6.00
July 21, 2005 31/2 Digit LCD, Low Power Display, A/D Converter with Overrange Recovery
The Intersil ICL7136 is a high performance, low power 31/2
digit, A/D converter. Included are seven segment decoders,
display drivers, a reference, and a clock. The ICL7136 is
designed to interface with a liquid crystal display (LCD) and
includes a multiplexed backplane drive.
The ICL7136 brings together a combination of high
accuracy, versatility, and true economy. It features auto-zero
to less than 10пЃ­V, zero drift of less than 1пЃ­V/oC, input bias
current of 10pA (Max), and rollover error of less than one
count. True differential inputs and reference are useful in all
systems, but give the designer an uncommon advantage
when measuring load cells, strain gauges and other bridge
type transducers. Finally, the true economy of single power
supply operation, enables a high performance panel meter
to be built with the addition of only 10 passive components
and a display.
The ICL7136 is an improved version of the ICL7126,
eliminating the overrange hangover and hysteresis effects,
and should be used in its place in all applications. It can also …
