AMS 6915 – Mini Pressure Sensor with I2C Interface

Data Sheet
Flyer

AMS 6915 is a series of board mountable digital pressure sensors in a compact DIL package with horizontal or vertical tube fittings. The calibrated and temperature compensated sensors with I2C-interface have an operating temperature range of -25 .. 85 °C and are especially suitable for microcontroller applications. Ultra low pressure variants are available for differential pressure measurements down to ±2.5 mbar.
