The HP03S includes a piezo-resistive pressure sensor and an ADC interface. It provides16 bit word data for pressure and temperature related voltage. With the helpof a highly accurate calibration of the senor, 10 unique coefficients were storedon the chip, thus accurate pressure and temperature reading can be realized.HP03S is a low power, low voltage device with automatic power down switching.I2C Serial Interface is used for communications with a microprocessor. Sensor packagingoptions are DIP or SMD (with metal cap) FeaturesIntegrated pressure sensor Pressure range: 300-1,100HPa 16 bit ADC 11 coefficients for software compensation stored on chip I2C serial interface One system clock line (32,768Hz) One hardware controlled reset line Low voltage, low power 15 bit ADC resolution Supply voltage: 2.0V-5.0V -30癈 to + 85癈 operating range producing area:China
