ICL7107 - Digit A/D Converter

The Maxim ICL7106/ICL7107 are monolithic analog-todigital converters (ADCs).

They have very high input impedances and require no external display drive circuitry.

On-board active components include polarity and digit drivers, segment decoders, voltage reference and a clock circuit.

• of these converters. The dual-slope conversion technique automatically rejects interference signals common in industrial environments. The true differential input and reference are particularly useful when making ratiometric measurements (ohms or bridge transducers). Maxim has added a zero-integrator phase to the ICL7106 and ICL7107, eliminating overrange hangover and hysteresis effects. Finally, these devices offer high accuracy by lowering rollover error to less than one count and zero reading.
