The Maxim ICL7106/ICL7107 are monolithic analog-to-

digital converters (ADCs). They have very high input

impedances and require no external display drive cir-

cuitry. On-board active components include polarity and

digit drivers, segment decoders, voltage reference and

a clock circuit. The ICL7106 will directly drive a nonmulti-

plexed liquid crystal display (LCD), whereas the ICL7107

will directly drive a common anode light emitting diode

(LED) display.

Versatility and accuracy are inherent features of these

converters. The dual-slope conversion technique auto-

matically rejects interference signals common in industri-

al environments. The true differential input and reference

are particularly useful when making ratiometric measure-

ments (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

drift to less than 1FV/NC.

These devices are used in a wide range of digital panel

meter applications. Most applications, however, involve

the measurement and display of analog data.

The "Maxim Advantage" signifies an upgraded quality level. At no additional cost we offer a second-source device that is subject to

the following: guaranteed performance over temperature along with tighter test specifications on many key parameters; and device

enhancement, when needed, that result in improved performance without changing the functionality.
