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.
