ICL7116

Description

The Intersil ICL7116 are high performance, low power, 3

segment decoders, display drivers, a reference, and a cl ock. The ICL7116 is designed to interface with

a liquid crystal display (LCD) and includes a multiplexed backplane drive.The ICL7116 have all of the featur

es of the ICL7106 with the additi on of a HOLD Reading input.

With

this input, it is possible to make a

measurement and retain the value on the display indefinitely. To make room for this feature the reference

low input has been connected to Common internally rather than being fully differential.

These circuits retain the accuracy, versatility, and true economy of the ICL7106. They feature

auto-zero to less than 10µV, zero drift of less than 1µV/

over error of less than one count. The versatility of true different ial input is of particular advantage when

measuring load cells, strain gauges and other bridge-ty pe transducers. And finally, the true

economy of

single power supply operation (ICL7116) enables a high performance panel me ter to be built with the addition

of only eleven passive components and a display.
