General description Pressure transducer HPSD 4000 is an OEM pressure sensing device. Signal conditioning consist of complete temperature compensation and adjusted amplifier in single, programmable ASIC. High performance and accuracy enables use of this transducer in many applications. Programmable temperature compensation provides 1% total error over 0 to 70°C temperature range. Standard ratiometric 0,5 to 4,5 V and I2C digital output at the same time give OEM users maximum freedom for any type of application with dry air or non-corrosive gases and liquids. The whole group consists for pressure ranges from 10 mbar to 7 bar. Differential and absolute versions are available for this transducer group. Features • Single 5 V supply voltage • Easy to use package • Wide compensated range (0 to 70°C) • Total accuracy down to 1% over 0 to 70°C, all effects included (maximum) • Standard 0,5 to 4,5 V voltage output • Up to 15 bits I2C output (pressure + temperature) • High performance OEM applications • Differential and absolute pressure configurations • Pressure ranges: from 10 mbar to 7 bar Competitive sensor & power supply solutions worldwide HVAC Medical instrumentation Respirators Air flow monitoring Process control Leak detection Altimeters

HPSD 4000 Pressure Transducer Over pressure is the maximum pressure which may be applied without causing damage to the sensing element. Burst pressure is the maximum pressure which may be applied without causing leakage damage to the sensing element. Analog output signal is ratiometric to power supply Vcc, digital signal is not ratiometric to the power supply. Offset voltage is the voltage output at zero pressure. Full scale output is the voltage output at full pressure range. Full scale span is the algebraic difference between the output at full scale pressure range and offset. Digital output...

STOP condition (P): is generated in transition of SDA line from LOW(H) to HIGH(L) when SCL line (clock) is HIGH. It can be only generated by the master. Each data request needs to end with STOP condition. DATA valid (D): Data is transmitted in byes (8 bits) starting with pressure data (2 bytes) with the MSB (most significant bit) first and followed by 2 bytes of temperature data with MSB first. Each data bit is transferred with each clock pulse. Valid data are presented after start condition when data line is stable during HIGH clock is generated. SDA changes must be done while clock is LOW. ACKNOWLEDGE...
