MCP9604T-E/3YW

Sensor And Detector Interfaces Overview

The MCP9604T-E/3YW is a four-channel thermocouple signal conditioning integrated circuit manufactured by Microchip Technology. It converts electromotive force signals from thermocouples into digital temperature values using NIST ITS-90 coefficients, supporting types K, J, T, N, S, E, B, and R. The device integrates cold junction compensation, open/short circuit detection, and programmable digital filtering. It operates on a supply voltage ranging from 2.7 V to 5.5 V with a typical current consumption of 300 µA. Accuracy specifications include a typical precision of ±0.5°C and a maximum error of ±1.5°C. Communication is handled via an I²C compatible interface, allowing up to eight devices on a single bus.
