The DPS422 is a miniaturized digital barometric air pressure and temperature sensor with high accuracy and low current consumption. Pressure sensing is carried out using a capacitive sensor element, guaranteeing high accuracy over temperature. The small 2.0 x 2.5 x 0.73 mm package makes the DPS422 ideal for mobile applications and wearable devices
The pressure and temperature sensor elements are measured by a 24-bit ΣΔ ADC. Measurement results can be accessed over I2C or SPI, with an optional configurable interrupt and a result FIFO capable of holding 32 pressure and/or temperature measurements
