General Description

The Maxim ICL7116 and ICL7117 are 3? digit monolithic analog-to-digital converters. They differ from the Maxim ICL7106 and ICL7107 in that the ICL7116 and ICL7117 have a Hold pin, which makes it possible to hold or “freeze” a reading. These integrating ADCs have very high input impedances and directly drive LCD (ICL7116) and LED (ICL7117) displays.

Features

● Improved 2nd Source!

● Hold Pin Allows Indefinite Display Hold

● Guaranteed First Reading Recovery from Overrange

● On-Board Display Drive Capability—No External Circuitry Required: LCD (ICL7116), LED (ICL7117)

● High-Impedance CMOS Differential Inputs

● Low Noise (< 15μVP-P) Without Hysteresis or Overrange Hangover

● Clock and Reference On-Chip

● Zero Input Gives Zero Reading

● True Polarity Indication for Precision Null Applications

Applications

These devices can be used in a wide range of digital panel meter applications. Most applications, however, involve the measurement and display of analog data:

● Pressure

● Voltage

● Resistance

● Temperature

● Conductance

● Current

● Speed

● Material Thickness
