DESCRIPTION

· The ICL7136 is a high-performance, low-power 3½-digit A/D converter with LCD display capabilities.
· It integrates seven-segment decoders, display drivers, a reference, and a clock.
· Designed for LCD interfacing, it includes a multiplexed backplane drive.
· Offers high accuracy, versatility, and cost-efficiency with features like auto-zero and low input bias current.
· Suitable for measuring devices like load cells and strain gauges due to its true differential inputs and reference.
· Operates on a single power supply, requiring only 10 passive components and a display for a high-performance panel meter.
· Improved version of ICL7126, eliminating overrange hangover and hysteresis effects.
· Can replace ICL7106 in various applications with minimal component changes.

FEATURES

· Recovers from first reading overrange in one conversion period.
· Ensures zero reading for 0V input across all scales.
· Provides true polarity at zero for accurate null detection.
· Features 1pA typical input current.
· Includes true differential input and reference with direct LCD drive.
· Low noise, less than 15µV P-P.
· On-chip clock and reference, no additional active circuits needed.
· Low power consumption, less than 1mW.
· Available in surface mount package.
· Drop-in replacement for ICL7126 with no changes required.
· Pb-Free plus Anneal available, RoHS compliant.

APPLICATIONS

· Ideal for high-performance panel meters.
· Suitable for measuring load cells, strain gauges, and other bridge-type transducers.
· Can be used in a wide variety of applications as a plug-in replacement for ICL7106.
