Overview
The ADT7411ARQZ, produced by Analog Devices Inc., is a versatile integrated circuit that combines a 10-bit digital temperature sensor with an 8-channel analog-to-digital converter (ADC). This device is packaged in a 16-lead QSOP and operates from a single supply voltage ranging from 2.7 V to 5.5 V. It features a band gap temperature sensor and a 10-bit ADC, allowing for precise temperature measurements with a resolution of 0.25°C and an accuracy of ±0.5°C over a temperature range of −40°C to +120°C.
