Esittely

WF490RE is a highly integrated, low-power single-chip ASK/OOK RF receiver chip. The high-frequency signal receiving function is fully integrated in the chip to achieve the most reliable reception effect with the least peripheral devices and the lowest cost. Siksi, it is a single-chip receiving device withwireless high-frequency modulation signal input and digital demodulation signal outputin the true sense.
WF490RE is a SOP8 package with a normal operating voltage range of 2.0-5.5V, a normal operating current of 5mA, a startup time of 8ms, and a maximum receiving sensitivity of -113dBm, which is very suitable for various low-power devices. All RF and IF tuning are automatically completed in the chip, and the manual adjustment process is omitted in development and production, thereby reducing costs and accelerating product launch.
