General Description
The AS5209 is a digital pressure sensor especially designed for applications requiring highly-precision pressure measurement like Inflatable pump and tyre pressure applications. It is both a pressure and temperature sensor housed in a compact 3.0×3.76×1.3 mm3 package. The pressure sensor is based on the industry-recognized piezo-resistive technology featuring long-term stability and EMC robustness. A high-performance 24-bit ADC provides pressure resolution up to 0.35Pa, and temperature resolution up to 0.10℃. The pressure sensor has a wide operating range from 0kPa to 1500kPa that covers all surface elevations on earth. The device supports I2C compatible interface control. The interface operation voltage is from +3.0V to +3.6V, as well as programming additional registers on the device.The I2C address of AS5209 is 0x3Ah, only when the master device initiates the correct address, AS5209 generates an acknowledge condition and works normal. The device is a RoHs and Green compliant 8-pin LFBGA (3.0mm x 3.76mm x 1.3mm) outline dimension package.
