Overview
The AD7817BRUZ-REEL7, produced by Analog Devices Inc., is a 10-bit, 4-channel analog-to-digital converter (ADC) with an integrated on-chip temperature sensor. This device operates from a single power supply voltage ranging from 2.7 V to 5.5 V. It features a successive-approximation converter based on a capacitor digital-to-analog converter (DAC), an on-chip clock oscillator, inherent track-and-hold functionality, and an on-chip 2.5 V reference. The temperature sensor can be accessed via Channel 0, providing a temperature measurement with an accuracy of ±2°C and a resolution of ±0.25°C.
