The HP206F employs a MEMS pressure sensor with an I2C interface to provide accurate Temperature, Pressure or Altitude data. The sensor Pressure and Temperature outputs are digitized by a high resolution 24-bit ADC. The Altitude value is calculated by a specific patented algorithm according to the pressure and temperature data. Data compensation is integrated internally to save the effort of the external host MCU system. Easy command-based data acquisition interface and programmable interrupt control is available. Typical active supply current is 5.3 uA per measurement-second while the ADC output is filtered and decimated by 256. Pressure output can be resolved with output in fractions of a Pascal, and Altitude can be resolved in 0.01 meter. The HP206F is offered in a 6.3 mm x 6.9 mm x 3.1 mm package and specified for operation from -40°C to 85°C.
