The AD7652 is a 16-bit, 500 kSPS unipolar ADC with an analog input voltage range of 0V to 2.5V. It has no pipeline delay and supports both parallel and serial interfaces. The ADC is suitable for applications such as data acquisition, instrumentation, digital signal processing, spectrum analysis, medical instruments, battery-powered systems, and process control.
The AD7652 is a 16‑bit, 500 kSPS charge‑redistribution SAR analog‑to‑digital converter that operates from a single 5 V supply. It includes an internal reference, error‑correction circuitry, and supports both parallel and 2‑wire serial interfaces compatible with 3 V and 5 V logic levels.
The device is offered in 48‑lead LQFP and LFCSP packages and is specified for operation from –40 °C to +85 °C. Key specifications include 16‑bit resolution, 0 V‑2.5 V unipolar input range, typical power dissipation of 65 mW, and an internal reference voltage of 2.5 V with 7 ppm/°C drift. Applications cover data acquisition, instrumentation, DSP, spectrum analysis, and medical instruments.
