Low Power, CWA, Digit AID Converter
- —_ General Description
The Maxim ICL7137 is a monolithic analog to digital
converter with all the necessary active devices to directly
interface with a light emitting diode (LED) display.
Fen tures
. Improved 2nd Source! (see 3rd page for
"Maxim Advantage"'")
Excluding the LED display current, the ICL7137 supply . Guaranteed first reading recovery from overrange
current is under 200PA, making it suitable for battery . Zero Input Gives Zero Reading
operation. . Drives LED Displays Directly
Versatility and accuracy are inherent features of -
this converter. The dual-slope conversion technique . 2gr'alti'eehte,t2'f without hysteresis or
automatically rejects interference signals common in _ g g
industrial environments. Thetruedifferential input and . True Differential Reference and Input
reference are particularly useful when making ratio-
metric measurements (ohms or bridge transducers), . Monolithic, Low Power CMOS Design
and the zero-integrator phase in Maxim's ICL7137
eliminates overrange hangover and hysteresis effects.
Finally, this device offers high accuracy by lowering
rollover error to less than one count and zero reading .
drift to less than 1pV/°C. Ordering Information
