Overview
The AD7865BSZ-3, produced by Analog Devices Inc., is a high-performance, four-channel simultaneous sampling 14-bit analog-to-digital converter (ADC). This component operates from a single +5 V supply and features a 2.5 µs successive approximation ADC, four track/hold amplifiers, a 2.5 V reference, an on-chip clock oscillator, and signal conditioning circuitry. It also includes a high-speed parallel interface. The AD7865BSZ-3 is designed to sample input signals on four channels simultaneously, preserving the relative phase information of the signals. This makes it ideal for applications requiring precise and synchronized data acquisition.
