ICL7117, ICL7116 Datasheet (Maxim Integrated)

ICL7117, ICL7116, Digit A/D Converter

The Maxim ICL7116 and ICL7117 are 3½ 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 direct

* of these converters. The dual-slope conversion technique auto matically rejects interference signals common in industrial environments. The true differential input is particularly useful when making ratiometric measurements (ohms or bridge transducers). Maxim has added a zero-integrator phase to th
