Overview
The AD7655SCPZ-EP-RL is a low-cost, 4-channel, 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the PulSAR (Successive Approximation Register) ADC family and is designed for simultaneous sampling applications. It operates from a single 5 V power supply and features two low noise, wide bandwidth track-and-hold amplifiers, allowing for the simultaneous sampling of input pairs. The ADC includes an internal conversion clock, error correction circuits, and both serial and parallel system interface ports. It is particularly suited for applications requiring high sampling rates and low power consumption, with operation specified from −40°C to +85°C.
