wisesun WS480X

WS480X is a highly integrated, low-power monolithic ASK/OOK RF receiver IC. All high-frequency signal reception functions are integrated on-chip to achieve the most reliable reception performance with minimal external components and lowest cost. It is therefore a true single-chip receiver in the sense of "wireless HF modulated signal in, digital demodulated signal out."

The WS480X comes in a SOP8 package, with an operating voltage range of 2.0~5.5V, operating current of 3.8mA, startup time of 3ms, and a maximum receive sensitivity of -115dBm, making it ideal for various low-power applications. All RF and IF tuning is performed automatically on-chip, eliminating manual adjustment processes during development and production, thereby reducing costs and accelerating time-to-market.
