AMS 5812 OEM Pressure Sensor with Analog and I2C Output

AMS 5812 series are high-precision sensors with two different outputs, an analog output and a digital I2C output. The analog 0.5 to 4.5V output is ratiometric to the supply voltage and provides pressure measurement data only, while the I2C output provides pressure as well as temperature measurement data. Both outputs can be used simultaneously.

AMS 5812 sensors combine a micromachined, high quality piezoresistive pressure sensing element with a modern, signal conditioning CMOSASIC on a ceramic substrate. They are extensively calibrated and temperature compensated in a wide temperature range of -25 to 85 °C. This enables high precision measurements and excellent drift and long-term stability.

AMS 5812 pressure sensors come in a compact and robust dual in-line ceramic package (DIP) for assembly on printed circuit boards (PCBs). Two package variants are available: one with vertical pressure ports for hose connection and one for O-ring sealing (N-package type for manifold mount). The sensors are operational without any additional components. 

AMS 5812 series are available for all pressure types in various pressure ranges: differential (relative) pressure sensors in ranges from 0 … 0.054 psi up to 0 … 100 psi, absolute pressure types for 0 … 5 psi up to 0 … 30 psi and 11 … 17.5 psi for barometric measurements. Bidirectional differential sensors are available from -0.054 … +0.054 psi up to -15 … +15 psi up to -15 … +15 psi. Custom specific pressure ranges and modifications are available on request.
