0 - 10 Bar Absolute MEMS Piezo Resistive Pressure Sensor ASIC Signal Management

TM-PS0316 Series

Pressure sensors

Description

PS0316 series are designed by a mixed package where the silicon pressure sensor and signal processing circuit are packaged into an integral pressure chip. Furthermore, PS0314 series can offer compact design, high accuracy, greatest possible operational reliability, and other numerous options.

Active temperature compensation and linear calibration ensures that the analog signal output of the chip is proportional to the supply voltage and led to a linear function to the input pressure.

Customer - specific sensor characteristics can also be defined although the model PS0314 ensures a wide range of operating pressure, while its typical supply voltage is 5±0.5 V and current is 2.0 mA.

Note:

1. The module output is proportional linear in the operating voltage range.

2. Minimum pressure offset: an output voltage of the module under the minimum pressure within the pressure range.

3. Full range output: an output voltage of the module under the maximum pressure within the pressure range.

4. Full range span: an algebraic difference between the output value at maximum pressure and the output value at minimum pressure

within the pressure range.

5. Accuracy includes linearity, temperature hysteresis, zero offset and end value deviation (corresponds to measured error).

6. Response time: the time required to go from 10% of the output to 90% of the theoretical value.

7. Pre-treatment time: the time to take for stability after the pressure stabilizes.

8. Offset stability: the output offset of the module after a pulse pressure and temperature cycle for 1000 hours.

Limit parameters

Maximum rating value(1)

Note:

1. Maximum rating value will result in parameter degradation or device damage.

2. The maximum input & output current is controlled by the impedance between the ground and the power supply in the actual circui
