ICL7136CM44ZT

ADCs/DACs - Special Purpose Overview

The ICL7136CM44ZT is a low-power, 3½-digit analog-to-digital converter (ADC) with an integrated LCD driver. Manufactured by Renesas Electronics Corporation, this component operates on a single 9V power supply and features a 44-MQFP surface-mount package. It provides direct drive capability for liquid crystal displays, eliminating the need for external multiplexing circuitry in many applications.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 3½-digit ADC with direct LCD driver output
• Single 9V power supply operation
• 44-pin MQFP (10x10mm) surface-mount package

ADCs/DACs - Special Purpose Applications

• Battery-powered digital multimeters
• Portable industrial measurement instruments
• Low-power data acquisition systems

ADCs/DACs - Special Purpose Procurement Notes

Verify component status as the ICL7136 series is generally listed as obsolete or discontinued by major distributors. Confirm RoHS compliance status, as earlier versions of this part may not meet current environmental regulations. Check for lead-free alternatives if required for specific manufacturing standards.

ADCs/DACs - Special Purpose Selection Notes

Select this part when a monolithic solution combining ADC and display driving is required to minimize board space. Ensure the application supports single-supply 9V operation. Consider the 44-MQFP footprint constraints during PCB layout design compared to through-hole DIP alternatives.

ADCs/DACs - Special Purpose Part Context

This component belongs to the ICL7136 family of dual-slope integrating ADCs originally developed by Intersil and later acquired by Maxim Integrated and Renesas. It is designed specifically for high-accuracy DC measurements where low power consumption and minimal external components are critical.
