ICL7116/ICL7117
General Description
The Maxim ICL7116 and ICL7117 are 3? digit monolithic
analog-to-digital converters. They differ from the Maxim
ICL7106 and ICL7107 in that the ICL7116 and ICL7117
have a Hold pin, which makes it possible to hold or
“freeze” a reading. These integrating ADCs have very
high input impedances and directly drive LCD (ICL7116)
and LED (ICL7117) displays.
Versatility and accuracy are inherent features of these
converters. The dual-slope conversion technique auto-
matically rejects interference signals common in industrial
environments. The true differential input is particularly
useful when making ratiometric measurements (ohms or
bridge transducers). Maxim has added a zero-integrator
phase to the ICL7116 and ICL7117, 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 1μV/oC.
Applications
These devices can be used in a wide range of digital
panel meter applications. Most applications, however,
involve the measurement and display of analog data:
● Pressure ● Conductance
● Voltage ● Current
● Resistance ● Speed
● Temperature ● Material Thickness
3? Digit ADCs with Display Hold
Features
● Improved 2nd Source!
● Hold Pin Allows Indefinite Display Hold
● Guaranteed First Reading Recovery from Overrange
● On-Board Display Drive Capability—No External
Circuitry Required: LCD (ICL7116), LED (ICL7117)
● High-Impedance CMOS Differential Inputs
● Low Noise (< 15μV P-P ) Without Hysteresis or
Overrange Hangover
● Clock and Reference On-Chip
● Zero Input Gives Zero Reading
● True Polarity Indication for Precision Null Applications
