ICL7136CPL

ADCs/DACs - Special Purpose Overview

The ICL7136CPL+ is a low-power, 3½-digit analog-to-digital converter (ADC) with direct LCD drivers, manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single 9V supply with a maximum current consumption of 100 µA and power dissipation of 611 mW. The device features a maximum clock frequency of 48 kHz and supports 7-segment displays. Housed in a 40-pin PDIP package for through-hole mounting, it functions within an operating temperature range of 0°C to +70°C.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 3½-digit A/D conversion with direct LCD driver outputs
• Low power consumption: 100 µA max supply current at 9V
• 40-pin PDIP through-hole package for standard PCB mounting
• Operates within commercial temperature range (0°C to +70°C)

ADCs/DACs - Special Purpose Applications

• Battery-powered digital panel meters
• Industrial process control instrumentation
• Portable test equipment requiring low power ADCs

ADCs/DACs - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status via official datasheets. Check availability as distribution may be limited; some sources indicate restricted sales in certain regions. Ensure ordering suffixes match required specifications without assuming functional changes.

ADCs/DACs - Special Purpose Selection Notes

Select this part for applications requiring a complete 3½-digit ADC solution with integrated display drivers. Compare against ICL7136 variants like ICL7136CMH or ICL7136CQH for different package options such as PLCC or MQFP if surface mount is preferred. Verify voltage requirements align with the fixed 9V single-supply operation.

ADCs/DACs - Special Purpose Part Context

The ICL7136 series belongs to the classic Intersil/Maxim family of dual-slope integrating ADCs. It serves as a foundational component for 3½-digit display systems. Related parts include the ICL7135 (2½-digit) and ICL7137 (3½-digit with LED drivers). The CPL suffix specifically denotes the 40-pin plastic DIP package variant.

ADCs/DACs - Special Purpose Replacement Considerations

Direct substitutes include ICL7136CMH (44-MQFP), ICL7136CQH (44-PLCC), and ICL7136CPLZ (Renesas version). Verify pin compatibility and package dimensions when replacing across manufacturers or package types.
