AMS 5915 – Board-Mount Pressure Sensor with I2C Output

Data Sheet
Flyer

AMS 5915 is a series of high precision, digital pressure sensors with I2C output especially suitable for 3.3 V microcontroller applications. AMS 5915 pressure sensors are calibrated and compensated in a wide temperature range of -25 .. 85 °C leading to a low overall error (TEB) and have an excellent long-term stability due to their high quality electrical components housed in a ceramic dual in-line package (DIP). The compact PCB-mountable pressure sensors are available with vertical metal pressure ports for hose connection or without metal pressure ports for o-ring sealing. The sensors in the AMS 5915 series are available for various pressure types and multiple pressure ranges from -2.5 … 2.5 mbar up to 16 bar.
