AD7688 is a 16-Bit, 1.5 LSB INL, 500 kSPS PulSAR™ Differential ADC in MSOP/QFN package.
The AD7688 is a 16‑bit, charge‑redistribution successive‑approximation ADC that operates from a single 5 V supply. It offers true differential inputs, a serial SPI/QSPI interface, and optional daisy‑chain capability, making it suitable for battery‑powered and high‑speed data‑acquisition applications.
The device is available in 10‑lead MSOP and 10‑lead QFN (LFCSP) packages, operates from –40 °C to +85 °C, and provides low standby current (1 nA) with power dissipation as low as 3.75 µW at 100 SPS.
