MS7902
PRESSURE SENSOR DIE (0-2 BAR)
• 0 to 200 kPa range (2 bar or 29 PSI)
• Absolute/differential pressure sensors
• High linearity, small size
• RoHS-compatible & Pb-free1
DESCRIPTION
The sensor element of the MS7902 consists of a silicon micro-machined membrane. Implanted resistors make
use of the piezo-resistive effect to sense the membrane deflection and transform it in an electrical signal. This
sensor, which has outstanding linearity and span values, is available in various configurations. The absolute
pressure sensor employs a sealed vacuum reference cavity underneath the membrane. The Pyrex glass wafer
used for this sealing has a thickness of 0.2 mm (MS7902-A_0.2) or 0.5 mm (MS7902-A_0.5). There are two
gauge versions available: one with a drilled Pyrex glass (MS7902-D) and the other without Pyrex glass
(MS7902-S).
FEATURES
• Uncompensated pressure sensor die
• Output span 150mV @ 5V
• Temperature range -40°…+125°C
• Linearity 0.05% (typical)
• Very small die size 1.72 x 1.58 mm (MS7902-A)
• Low cost, high reliability
APPLICATION
• Absolute pressure sensor systems
• Differential/gauge pressure sensor systems
• Engine controls
• Dive computers
