PRELIMINARY
MS7212-A2 Hermetic Pressure Sensor Die (0-12 bar)
• 0 to 1200 kPa range (12 bar or 174 PSI)
• Absolute pressure sensor
• Hermetic sensor, temperature up to 150°C
• Pads on one side
• For harsh environment
• RoHS-compatible & Pb-free1
DESCRIPTION
The MS7212-A2 is an absolute silicon micro-machined pressure sensor for harsh environment, with the pads on
one side. A vacuum reference cavity is sealed on top of the sensitive silicon membrane by the anodic bonding of
a glass cap. The pressure, applied on the backside, is converted in electrical signal by piezo-resistors implanted
in the silicon membrane. To improve the sensor stability, a drilled glass is bonded on the backside. As the
pressure port consists of glass and silicon, both stable in most of the chemicals, the MS7212-A2 is suitable for
media-resistive applications.
FEATURES
• Media resistive pressure sensor die
• Output Span 150 mV @ 5 V
• Temperature Range -40 °C … + 150 °C
• Linearity 0.05 % (typical)
• Die size 1.73 x 1.18 mm2
• Low Cost, High reliability
APPLICATIONS
• Harsh environments
• Absolute pressure sensor systems
• Braking systems
• Tire pressure
• Engine controls
• Oil pressure
