Overview
The ADT7411ARQZ-REEL, produced by Analog Devices Inc., is a versatile and highly integrated electronic component that combines a 10-bit temperature-to-digital converter with an 8-channel analog-to-digital converter (ADC). This device is housed in a 16-lead QSOP package 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, enabling precise temperature monitoring and digitization with a resolution of 0.25°C. The ADT7411 also supports multiple serial interface options, including SPI, QSPI, MICROWIRE, and I2C/SMBus, making it suitable for a wide range of applications.
