Descriptions
The HP206C 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 HP206C is offered in a 6.8 mm x 6.2 mm x 0.635(+0.2) mm
package and specified for operation from -40°C to 85°C.
