ICL7136CMH+D

ADCs/DACs - Special Purpose Overview

The ICL7136CMH+D is a low-power, 3 1/2 digit analog-to-digital converter (ADC) with integrated LCD drivers. Manufactured by Analog Devices Inc./Maxim Integrated, it utilizes a dual-slope integrating architecture to provide high accuracy and noise rejection. The device operates on a single 9V supply and features a maximum clock frequency of 48 kHz. It is housed in a 44-pin MQFP surface-mount package, suitable for applications requiring direct drive of liquid crystal displays without external multiplexing circuitry.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 3 1/2 digit ADC with direct LCD driver outputs
• Low power consumption with 100 µA maximum supply current
• Operates on a single 9V power supply
• Surface-mount 44-pin MQFP (10x10 mm) package

ADCs/DACs - Special Purpose Applications

• Digital panel meters
• Industrial process control instrumentation
• Portable battery-powered measurement devices

ADCs/DACs - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer. Confirm RoHS compliance status via official documentation. Check moisture sensitivity level (MSL 4) requirements for storage and handling. Ensure the specific suffix matches the required package variant. Review lead times as availability may be restricted.

ADCs/DACs - Special Purpose Selection Notes

Select this component for designs requiring a complete A/D conversion and display solution in a compact form factor. Compare against the ICL7135 series if higher resolution (4.5 digit) is needed. Verify that the 44-pin MQFP footprint aligns with PCB layout constraints. Ensure the 9V single-supply requirement fits the system power budget.

ADCs/DACs - Special Purpose Part Context

This part belongs to the ICL7136 family of integrating ADCs. It serves as a surface-mount equivalent to through-hole variants like the ICL7136CPL+. The 'CMH' designation indicates the plastic quad flat package variant. The '+D' suffix typically denotes lead-free and RoHS-compliant manufacturing standards within the Maxim Integrated product line.
