Analog Devices ADF7902 ISM Band FSK Receiver IC Datasheet
The ADF7902 is a single‑chip, low‑power UHF receiver designed for ISM‑band applications. It demodulates FSK signals with a 34.8 kHz deviation at data rates up to 2 kbps and offers eight selectable RF channels between 369.5 MHz and 395.9 MHz, controlled by three digital inputs.
The device operates from a 5 V supply, drawing 18.5 mA in normal receive mode and as little as 1 µA in standby. Detailed specifications, pin functions, typical performance plots, and example application circuits are provided to aid integration into microcontroller‑based designs.
