AD7693 is a 16-bit, ±0.5 LSB, 500 kSPS PulSAR Differential ADC in MSOP/QFN package.
The AD7693 is a 16‑bit successive‑approximation ADC offering up to 500 kSPS throughput, no missing codes, and a dynamic range of 96.5 dB. It operates from a single 5 V supply, supports 1.8 V‑5 V logic levels, and provides a serial SPI/QSPI/MICROWIRE interface with optional daisy‑chain and busy‑indicator features.
The device is offered in 10‑lead MSOP and 10‑lead QFN (LFCSP) packages, rated for –40 °C to +85 °C operation. Detailed specifications cover resolution, input range, power dissipation, timing parameters, absolute maximum ratings, and recommended PCB layout guidelines to separate analog and digital sections.
