MAX136

Low Power, 3 ⁄2 Digit A/D Converter

with Display Hold

General Description

Features

The MAX136 is a monolithic analog-to-digital converter

(ADC) with very high input impedance. It differs from the

Maxim ICL7136 in that the MAX136 provides a Hold pin,

which makes it possible to hold or "freeze" a reading. The

MAX136 directly drives a nonmultiplexed liquid crystal

(LCD) display, requiring no external drive circuitry. With

minor external component changes, it is pin compatible

with the ICL7116 but with significantly reduced power

consumption, making the MAX136 a superior device for

portable systems.

Versatility and accuracy are inherent features of this

ADC. The dual-slope conversion technique automatically

rejects interference signals common in industrial envi-

ronments. True differential inputs allow direct measure-

ments of bridge transducer outputs or load cells. The

zero-integrator phase eliminates overrange hangover

and hysteresis effects. The MAX136 offers high accuracy

by lowering rollover error to less than one count and zero

reading drift to less than 1µV/°C.
