Analog Devices AD7490 Datasheet
The AD7490 is a 12‑bit high‑speed, low‑power ADC offering up to 1 MSPS throughput. It operates from a single 2.7 V to 5.25 V supply and provides 16 single‑ended inputs with a programmable channel sequencer. The device features a low‑noise track‑and‑hold amplifier, flexible power/clock management, and a high‑speed serial interface (SPI/QSPI/MICROWIRE).
The part is available in 28‑lead TSSOP and 32‑lead LFCSP packages. Detailed specifications cover dynamic performance, timing, absolute maximum ratings, pin configurations, and typical performance characteristics, making the AD7490 suitable for microprocessor or DSP‑based data‑acquisition systems.
