Overview
The AD7865YSZ-1 is a high-performance, four-channel simultaneous sampling 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component operates from a single +5 V supply and features a successive approximation ADC with a conversion time of 2.5 µs. It includes four track/hold amplifiers, a 2.5 V reference, an on-chip clock oscillator, and signal conditioning circuitry. The AD7865YSZ-1 is designed to sample input signals simultaneously, preserving the relative phase information of the signals on the four analog inputs. It supports analog input ranges of ±10 V, ±5 V, or ±2.5 V and includes overvoltage protection up to ±20 V.
