General Description
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.
