TC7107CLW713

ADCs/DACs - Special Purpose Overview

The TC7107CLW713 is a 3-1/2 digit Analog-to-Digital Converter manufactured by Microchip Technology, housed in a 44-pin PLCC package. It features an internal precision reference with a typical temperature coefficient of 20 ppm/°C and operates on a single +5V supply. The device directly drives common anode LED displays with an 8 mA segment sinking current. Key electrical characteristics include a maximum power dissipation of 1.23 W, a maximum supply current of 1.8 mA, and a noise performance of 15 µV peak-to-peak. It supports commercial operating temperatures from 0°C to +70°C.

ADCs/DACs - Special Purpose Feature Summary

• Portable instrumentation utilizing low-power operation.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix '713' against official documentation to confirm tape-and-reel packaging details. Ensure the component meets humidity sensitivity requirements during storage and handling. Confirm that the 44-pin PLCC package dimensions align with the target PCB footprint before finalizing procurement orders.

ADCs/DACs - Special Purpose Selection Notes

Select this model for applications requiring direct LED display driving without additional buffer circuitry. Ensure the system design accommodates the 44-pin PLCC package size. Verify that the analog input range matches the 200 mV or 2 V full-scale options supported by the integrating resistor selection. Consider the 0°C to +70°C commercial temperature range for environmental suitability.

ADCs/DACs - Special Purpose Part Context

This component belongs to the TC7106/A and TC7107/A family of dual-slope integrating ADCs. It serves as a drop-in replacement for legacy TC7107 devices, allowing upgrades to existing systems without changing external passive component values.
