The AS55-01BA
The AS55-01BA-00 employs a MEMS pressure sensor with an I²C interface to provide accurate temperature,
pressure data. The sensor pressure and temperature outputs are digitized by a high resolution 24-bit ADC.
Data compensation is integrated internally to save the effort of the external host MCU system. Pressure
output can be resolved with output in fractions of Pascal.
