P1905
Backside Absolute
Pressure Sensor Die
The P1905 piezoresistive sensor die is designed for absolute pressure measurements in aggressive (harsh)
media. The die has a reference vacuum chamber formed by hermetic low-stress bonding of silicon cap to
the top side of device wafer. By applying pressure from backside of the die, P1905 sensor die eliminates
the direct contact of sensor circuitry on top side with the applied media, which allows the P1905 die to mea-
sure pressure in aggressive liquids and gases. With NovaSensor’s SenStable^® process, P1905 die features
excellent long-term stability and repeatability (< 0.1% / year typ.).
