MAX136
Low Power, 3 1 ? 2 Digit A/D Converter
with Display Hold
General Description
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.
