AMS 5812 - Pressure Sensor with Analog and Digital Output (I2C)

AMS 5812 is a series of high precision pressure sensors combining a ratiometric analog voltage output with a digital I2C output. They are calibrated and compensated in a temperature range of -25 ... 85 °C. The PCB- mountable sensors are available in a ceramic DIP package in variants with tube fittings or for o-ring sealing.
