AMS 5935 - 18 bit OEM Pressure Sensor with Digital Output (I2C)

Datasheet

The digital 18 bit board-mount pressure sensors in the AMS 5935 series are designed for high precision measurements in low and ultra-low pressure ranges. They combine very high measurement accuracy with extremely low power consumption. The AMS 5935 are 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 the extremely low current consumption in sleep mode, the AMS 5935 pressure sensors are especially suitable for battery powered microcontroller applications.
