ICL7136CMH+TD

ADCs/DACs - Special Purpose Overview

The ICL7136CMH+TD is a low-power, 3½-digit analog-to-digital converter (ADC) with an integrated LCD driver, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 9V supply and consumes a maximum of 100 µA. The device features a dual-slope integration architecture with a maximum clock frequency of 48 kHz. Packaged in a 44-MQFP (10x10 mm) surface-mount format, it supports direct driving of seven-segment LCD displays. The operational temperature range extends from 0°C to +70°C, making it suitable for battery-powered instrumentation applications requiring minimal power consumption.

ADCs/DACs - Special Purpose Feature Summary

ADCs/DACs - Special Purpose Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated for this specific part number. Confirm the 44-MQFP package dimensions and pinout compatibility with the target PCB layout. Ensure the design accommodates the single 9V supply requirement and the 0°C to +70°C operating temperature range. Check for RoHS compliance status if required by local regulations.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a combined ADC and LCD driver solution is needed to reduce board space and component count. The ICL7136CMH+TD is appropriate for designs prioritizing ultra-low current draw over high-speed conversion. Compare against the ICL7136CPL+ if a through-hole DIP package is preferred instead of surface mount. Ensure the application does not require higher resolution than 3½ digits or LED display output.

ADCs/DACs - Special Purpose Part Context

This part belongs to the ICL7136 series of three-and-a-half-digit A/D converters. It is functionally equivalent to other variants like the ICL7136CPL+ but differs in packaging. The CMH suffix indicates the 44-lead MQFP surface-mount package. Related parts include the ICL7137 series, which offers similar functionality with potential interface variations.

ADCs/DACs - Special Purpose Replacement Considerations

The ICL7136CMH+D is listed as a direct substitute. The ICL7136CMH+TD is also noted as a similar alternative. For through-hole requirements, the ICL7136CPL+ serves as a package-compatible replacement. Verify pinout compatibility before substitution.
