HOPERF HP02S

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.

I²C data input and output I2C clock input * XCLR is to reset the AD converter (active low). XCLR should be set to high only during AD conversion phase(reading T1,D1). While at all other states, such as reading calibration factors, this pin should be kept low.
