DIFFERENTIAL PRESSURE SENSOR
Differential Pressure Sensor -DR8696DDetailed Description：
WORKING PRINCIPLE：
The DR8696D pressure sensor adopts SMD package, integrates pressure sensitive element and digital conditioning chip, digitally compensates the offset, sensitivity, temperature drift and nonlinearity of pressure sensitive element, and takes the supply voltage as a reference to generate a calibrated and temperature compensated digital output signal.
