AD7663 is a 16-bit, 250 kSPS CMOS ADC produced by Analog Devices.
The AD7663 is a 16‑bit, 250 kSPS charge‑redistribution SAR analog‑to‑digital converter that operates from a single 5 V supply. It includes a high‑speed sampling ADC, resistor‑based input scaler for various voltage ranges, an internal conversion clock, error‑correction circuitry, and both serial and parallel system interfaces.
Key features include fast 250 kSPS throughput, low power dissipation (35 mW typical at full speed), superior INL of ±3 LSB with no missing codes, and flexible input configurations (bipolar and unipolar). The device is offered in 48‑lead LQFP and LFCSP packages and is rated for –40 °C to +85 °C operation.
