General
The HP03D 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, 10 unique coefficients were stored on the chip, thus accurate pressure and temperature reading can be realized. HP03D is a low power, low voltage device with automatic power down switching. I2C Serial Interface is used for communications with a microprocessor. Sensor packaging options are DIP or SMD (with metal cap)
