Analog Devices AD7910/AD7920 ADC Datasheet
The AD7910 (10‑bit) and AD7920 (12‑bit) are successive‑approximation ADCs designed for high‑speed, low‑power applications. They operate from a single 2.35 V to 5.25 V supply and deliver up to 250 kSPS throughput. Both parts include a low‑noise, wide‑bandwidth track‑and‑hold amplifier that can handle input frequencies above 13 MHz.
The devices are offered in 6‑lead SC70 and 8‑lead MSOP packages and feature flexible serial interfaces (SPI, QSPI, Microwire, DSP‑compatible). Power‑down mode reduces consumption to 1 µA (typical 50 nA). Detailed timing, pin configurations, and layout recommendations are provided for optimal performance.
