AT2310 High Accuracy Low Power Barometer Module

General Description

The Atmodule AT2310-16A precision digital-output pressure sensor uses smart sensor techniques to correct pressure readings for temperature and linearity, achieving a total error band of under 0.1% FS (0.016 PSI) over the -40 F to +185 F temperature range. The typical error band is 0.05% FS (0.008 PSI) over the -40 F to +185 F temperature range. Static accuracy is better than 0.004 PSI. The module contains a silicon pressure sensor, sensor interface electronics, a 21-bit A/D converter, EEPROM calibration memory, and a sensor signal processor. Operating from a 3.3 volt supply, the module is designed to be soldered onto the user's printed circuit board. The sensor element is protected with a gel coating and is compatible with non-condensing air.
