MEMS Gauge Pressure Sensor

2SMPP

Pressure cycle range (0 to 40 kPa)

Note: 1. Tested temperature condition: 25

°C

3. Rated cycle pressure: 0 to 40 kPa

4. These output voltage characteristics are measured with tester without a mounting board.

Example of application circuit for MEMS Pressure Sensor

1. The pressure sensor is designed to convert a voltage by means of constant current drive.

2. Please amplify the output voltage of the pressure sensor by using the amplifying circuit if necessary.
