Overview
The ADT7411ARQ-REEL, produced by Analog Devices Inc., is a versatile integrated circuit that combines a 10-bit temperature-to-digital converter with an 8-channel 10-bit 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 dual serial interface options, including SPI, QSPI, MICROWIRE, DSP, and SMBus/I2C, making it highly adaptable for various applications. The ADT7411ARQ-REEL includes a band gap temperature sensor and provides a resolution of 0.25°C for temperature measurements. It also offers eight single-ended analog input channels with configurable input ranges and internal averaging for noise reduction.
