Introduction

The XGZP6826D is a miniaturized Digital Barometric Air Pressure Sensor with a high accuracy and a low current consumption. The XGZP6826D is both a pressure and a temperature sensor. The XGZP6826D‘s internal signal processor converts the output from the pressure and temperature sensor elements to 24-bit results. Each pressure sensor has been calibrated individually and contains calibration coefficients. The coefficients are used in the application to convert the measurement results to true pressure and temperature values. Sensor measurements and calibration coefficients are available through the serial I2C interface.

Dimension&Electric Definition (Unit:mm) 

 

Notes:

1.Implement ESD protection during whole soldering and assembly process.

2.Overload voltage(max.6.5Vdc) or current(max.5mA) may burn the ASIC and cause the sensor fail throughly.

3.More detalis about soldering and storage etc., refer to Overall notes.
