TC7129CKW713

ADCs/DACs - Special Purpose Overview

The TC7129CKW713 is a 4-1/2 digit CMOS Analog-to-Digital Converter (ADC) designed for direct multiplexed LCD driving. It features ±19,999 count resolution with 10 µV sensitivity on the 200 mV scale and 110 dB common mode rejection ratio. The device operates on a single supply voltage ranging from 6 V to 15 V, consuming typically 500 µA at 9 V. It utilizes successive integration to achieve better than 0.005% accuracy without external phase compensation components.

ADCs/DACs - Special Purpose Feature Summary

Directly drives 4-1/2 digit multiplexed LCDs including decimal points and annunciators
Includes low battery detection, continuity indicator, and overrange/underrange outputs
Supports auto-ranging via range select input and latch-and-hold functionality
Internal phase compensation eliminates need for external RC networks

ADCs/DACs - Special Purpose Applications

Full-featured digital multimeters
High-resolution digital measurement devices
Battery-powered precision instruments

ADCs/DACs - Special Purpose Procurement Notes

Verify the '713' suffix indicates tape and reel packaging rather than tray. Confirm moisture sensitivity level handling requirements during assembly. Check current lifecycle status as older Microchip models may be subject to obsolescence notices.

ADCs/DACs - Special Purpose Selection Notes

Select this model for applications requiring 4-1/2 digit resolution with integrated display drivers. Ensure the design accommodates the 44-pin PQFP package. Verify that the application environment stays within the 0°C to +70°C operating temperature range.

ADCs/DACs - Special Purpose Part Context

This component belongs to the TC7129 family of 4-1/2 digit ADCs. It serves as a pin-compatible replacement for legacy ICL7129 parts, though internal phase compensation differences require removing external components present in older designs.
