Analog Devices AD7686 16‑Bit 500 kSPS PulSAR ADC Datasheet
The AD7686 is a 16‑bit, charge‑redistribution successive‑approximation ADC that operates from a single 5 V supply. It offers a 500 kSPS maximum throughput, no missing codes, and a versatile serial interface compatible with SPI, QSPI, Microwire and DSP protocols. The device is available in 10‑lead MSOP and QFN (LFCSP) packages and operates from –40 °C to +85 °C.
Key features include ±0.6 LSB typical INL, 92.5 dB SINAD at 20 kHz, –110 dB THD, ultra‑low standby current (1 nA), and optional daisy‑chain capability with a busy indicator. The ADC supports multiple logic levels (1.8 V, 2.5 V, 3 V, 5 V) via a separate VIO supply.
