TC7107RCPL

ADCs/DACs - Special Purpose Overview

The TC7107RCPL is a 3-1/2 digit analog-to-digital converter (ADC) manufactured by Microchip Technology. It features a dual-slope integration architecture with an internal reference voltage and direct LED display drive capability. The device operates on a single 5V supply, consuming approximately 1.8 mA of current. It provides high input impedance differential inputs and includes an auto-zero cycle to eliminate offset errors. Packaged in a 40-pin PDIP, it supports through-hole mounting and functions within a commercial temperature range.

ADCs/DACs - Special Purpose Procurement Notes

Verify the 'R' suffix indicates the specific commercial temperature grade variant when sourcing. Confirm package integrity for the 40-pin PDIP tube format upon receipt. Cross-reference the manufacturer part number with official Microchip documentation to ensure compatibility with existing PCB footprints and design specifications.

ADCs/DACs - Special Purpose Selection Notes

Select the TC7107RCPL for applications requiring direct LED display interfacing without external multiplexing drivers. Compare against the TC7106 series if LCD displays are preferred instead. Ensure the system power supply remains stable at 5V to maintain accuracy. Verify that the required resolution matches the 3-1/2 digit specification for the intended measurement range.

ADCs/DACs - Special Purpose Part Context

This component belongs to the TC7107A family of 3-1/2 digit ADCs designed for direct display driving. It serves as a cost-effective solution for replacing complex microcontroller-based display systems in dedicated instrumentation. The part integrates the ADC core and display driver logic into a single CMOS package.

ADCs/DACs - Special Purpose Replacement Considerations

The TC7107CPL is a verified functional substitute within the same product family. Both parts share identical pinouts and electrical characteristics, differing primarily in manufacturing lot or minor commercial grade variations. Verify temperature ratings match application requirements before substitution.
