AD7623 is a 16-bit, 1.33 MSPS PulSAR® ADC. It features high resolution, low distortion, no pipeline delay, and is suitable for applications such as medical instruments, high-speed data acquisition, digital signal processing, and communications.
The AD7623 is a 16‑bit, 1.33 MSPS charge‑redistribution SAR analog‑to‑digital converter that operates from a single 2.5 V supply. It provides a 2.048 V internal reference, differential input range up to ±2.5 V, and both parallel (8‑ or 16‑bit) and serial (SPI/QSPI/MICROWIRE/DSP‑compatible) interfaces. Typical power dissipation is 45 mW at full throughput.
The device is offered in 48‑lead low‑profile QFP and 48‑lead lead‑frame chip‑scale (LFCSP_VQ) packages. Layout guidelines stress separating analog and digital ground planes with a single star‑ground point, using large power traces and decoupling capacitors close to AVDD, DVDD and OVDD pins. An ordering guide lists part numbers for each package and temperature‑range option.
