2.2 Analog Interface

The analog output swings from 0 to 2V, with the valid working output ranging from 0.5V to 1.5V as

shown in Figure 5.

As pressure increases beyond the full scale range (FSR) the output will increase to 2V and then limit.

The sensor should be unloaded at power on to allow the sensor’s baseline to be registered correctly.

NOTE: An output below 0.5V may indicate negative pressures, which occur when the sensing area is

under tension. This should be avoided since it can damage the internal structure of the sensor.

NOTE: Sensor over pressure should be limited to less than 3x FSR to avoid damaging the sensor.
