AMS5935 is a digital 18 bit board-mount pressure sensor designed for high precision measurements in ultra-low and low pressure ranges.

They combine very high measurement accuracy with extremely low power consumption. The AMS 5935 is housed in a robust ceramic DIL-8 package for PCB assembly. They have an integrated I2C interface, which allows the readout of calibrated pressure and temperature data. They are extensively calibrated and temperature compensated and feature an extremely low measurement error at room temperature as well as a very small total error band in the compensated temperature range of -25 … 85 °C. With a supply voltage range of 1.7 V up to 3.6 V and extremely low current consumption in sleep mode, the AMS 5935 pressure sensors are especially suitable for battery-powered microcontroller applications.
