Low voltage, low power consumption Description The HP03 pressure module 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, 11 unique coefficients were stored on the chip, thus accurate pressure and temperature reading can be realized.
HM03 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) Features .
15 Bit ADC resolution .

I2C data input and output I2C clock input PIN Description Pin Name VSS VDD MCLK XCLR SDA SCL * XCLR is to reset the AD converter (active low).
XCLR should be set to high only during AD conversion phase(reading D1,D2), at all other states, such as reading calibration factors, this pin should be kept low.
* The quality of the MCLK signal can significantly influence the current consumption of the pressure module.
To obtain minimum current, remember to supply good quality MCLK signal Absolute Maximum Ratings Parameter Supply...
