Theory of operation SM5852

The SM5852 pressure sensors combine state of-the-art pressure sensor technology with signal conditioning to produce a fully signal conditioned, amplified, temperature compensated sensor in a dual in-line package (DIP) configuration. Combining the sensor and the signal conditioning circuitry in a single package simplifies the use of advanced silicon micro machined pressure sensors. No additional components are required for obtaining an amplified high level, calibrated pressure measurement.

The output signal is available at the analog output (0.5…4.5 V / 2.5 V ± 2 V ratiometric) and at the I²C-Bus-Interface.

Notice: Default address value of the I2C-Bus-Interface is 9510. This value can be modified from user’s side.
