Descriptions
The HP203B 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 5.3μA 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 0.1 meter. Package is surface mount with a stainless steel cap and is RoHS compliant.
