ICL7109CPL136 is listed in the Analog To Digital Converters (ADC) range at ChipApex. The manufacturer field lists Harris Corporation. Its product description is 8 BIT , 50MSPS VIDEO A/D CONVERT. Review the specifications below when checking this part for your BOM.
The ICL7109CPL136 is a 12-bit analog-to-digital converter (ADC) manufactured by Harris Corporation. It utilizes a dual-slope integrating architecture with a single differential input channel and parallel binary output interface. The device operates on ±5V power supplies and supports a sampling rate of 30 samples per second. Key electrical specifications include an integral nonlinearity (INL) of +/- 1 count and an external reference voltage requirement of 204.8 mV. The component is housed in a 40-pin PDIP package and is designed for through-hole mounting.
The ICL7109 series represents a class of high-precision integrating ADCs originally developed by Harris Semiconductor, now part of Analog Devices. These components are distinguished by their ability to provide high accuracy at low conversion speeds, making them suitable for applications where noise rejection and linearity are prioritized over throughput. The CPL136 suffix typically denotes specific packaging or tape-and-reel variations within the standard ICL7109 family.
Direct replacements include the ICL7109CPL+ from Analog Devices/Maxim Integrated, which maintains pin compatibility and functional equivalence. Designers should verify that the replacement source confirms the same 40-PDIP package dimensions and electrical characteristics, particularly the 204.8 mV reference voltage requirement.
