2SMPP-03 MEMS Gauge Pressure Sensor
2SMPP-03
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 amplifier the output voltage of the pressure sensor by using the amplifying circuit if necessary.
Engineering Data (for Reference)
■ Output Characteristics
Rated Pressure vs. Output Voltage
Note: 1. Ambient temperature condition: 23°C.
Note: 2. Drive current: 100 µA
Note: 3. These output voltage characteristics are measured with tester without a mounting board.
Note: 4. The output voltage characteristics may be influenced by the mounting board. Be sure to check operation including durability in actual equipment before use.
