ICL7126CPL+3

ADCs/DACs - Special Purpose Overview

The ICL7126CPL+3 is a low-power, 3 1/2-digit analog-to-digital converter (ADC) with an integrated LCD driver. Manufactured by Analog Devices Inc./Maxim Integrated, it operates on a single 9 V supply and dissipates 1 W of power. The device features a parallel interface and is housed in a 40-pin PDIP package. It supports through-hole mounting and functions within a commercial temperature range of 0°C to +70°C. This component serves as a complete solution for driving liquid crystal displays directly from analog input signals.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix designation (+3) against official Analog Devices documentation to confirm packaging or revision differences compared to the standard ICL7126CPL+. Confirm RoHS compliance status and current availability, as distribution channels may list varying stock levels or discontinuation notices for this specific variant.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a monolithic ADC-LCD driver combination is required for cost-sensitive applications. Ensure the design accommodates a 9 V single supply rail. Verify that the target display is a common-source LCD compatible with the internal driver outputs. Consider thermal management if ambient temperatures approach the upper limit of the 0°C to +70°C operating range.

ADCs/DACs - Special Purpose Part Context

The ICL7126 series belongs to the Maxim Integrated line of precision ADCs. The ICL7126 specifically targets applications needing a simple interface between analog sensors and visual indicators. The CPL+ suffix indicates a lead-free, RoHS-compliant version in a plastic DIP package. The +3 suffix typically denotes a specific tube packaging quantity or regional variant, distinct from the bare die or other packaging options.
