AD7910/AD7920 is a 6-lead SC70 packaged 10-/12-bit ADC with a throughput rate of 250 kSPS. It is suitable for applications such as battery-powered systems, personal digital assistants, medical instruments, mobile communications, instrumentation and control systems, data acquisition systems, high-speed modems, optical sensors, etc.
The AD7910 (10‑bit) and AD7920 (12‑bit) are successive‑approximation ADCs designed for battery‑powered, high‑speed applications such as PDAs, medical instruments, and data‑acquisition systems. They operate from a single 2.35 V to 5.25 V supply, provide up to 250 kSPS throughput, and feature low power consumption with a standby current of 1 pA.
The datasheet details electrical specifications, timing diagrams, absolute maximum ratings, and ordering information. Key parameters include a 71 dB SNR, 13.5 MHz full‑power bandwidth, and operation over –40 °C to +85 °C. Packages are available in 6‑lead SC70 and 8‑lead MSOP formats.
