Description

The ADF7902 is a low power UHF receiver. The device demodulates frequency shift keyed (FSK) signals with 34.8 kHz frequency deviation and at data rates of up to 2 kbps. There are eight specific RF channels ranging from 369.5 MHz to 395.9 MHz on which the receiver can operate. Each channel is selectable by configuring three digital control lines. The ADF7902 is designed for low power applications, consuming 18.5 mA (typical) during normal operation and 1 μA (maximum) in standby mode.
