The AD7652 is a 16-bit, 500 kSPS unipolar ADC with features including high throughput, 0-2.5V analog input voltage range, no pipeline delay, parallel and serial interfaces, etc.
The AD7652 from Analog Devices is a 16‑bit charge‑redistribution SAR analog‑to‑digital converter that operates from a single 5 V supply. It offers 500 kSPS throughput, an internal reference, and both serial and parallel interfaces, making it suitable for data acquisition, instrumentation, and medical devices.
The datasheet provides detailed specifications, pin descriptions, timing diagrams, absolute maximum ratings, and application hints for extending the input range. It also includes layout guidance and ordering information for the 48‑lead LQFP and LFCSP packages.
