Analog Devices AD7656A ADC Datasheet
The AD7656A integrates six independent 16‑bit SAR ADCs in a single 64‑pin LQFP package, offering true bipolar analog inputs selectable for ±10 V or ±5 V ranges. It features parallel and high‑speed serial interfaces, including SPI/QSPI/MICROWIRE compatibility, and supports daisy‑chain operation.
Designed with iCMOS® technology, the device provides a 250 kSPS throughput, 12 MHz input bandwidth, 86.5 dB SNR, and low power consumption (140 mW at 250 kSPS, 5 V). The datasheet includes detailed pin configurations, timing specifications, absolute maximum ratings, and typical performance graphs. This manual is written in Chinese.
