Overview
The AD7417ARZ-REEL, produced by Analog Devices Inc., is a versatile 10-bit, 4-channel analog-to-digital converter (ADC) that includes an on-chip temperature sensor. This device operates on a single power supply ranging from 2.7 V to 5.5 V, making it suitable for a variety of applications where both analog data acquisition and temperature monitoring are required. The AD7417 features a successive approximation converter, a 5-channel multiplexer, and a built-in clock oscillator, eliminating the need for an external clock during conversion.
