Description

The HP02S includes a piezo-resistive pressure sensor and an ADC interface. It provides

16 bit word data for pressure and temperature related voltage. With the help of a highly

accurate calibration of the senor, 5 unique coefficients were stored on the chip, thus

accurate pressure and temperature reading can be realized. HP02S is a low power, low

voltage device with automatic power down switching.

I

communications with a microprocessor.

. 0

° C to + 50° C operating range

Applications

. Pressure measurement and control systems

. Mobile altimeter/barometer systems

. Weather forecast products

. Adventure or multi-mode watches
