PRESSURE SENSOR DIE (0-300 mmHg)
MS763
• 0 to 300 mmHg range (0.4 bar or 5.8 PSI)
• Absolute or differential pressure sensors
• Medical applications
• RoHS-compatible & Pb-free1
DESCRIPTION
The MS763 is a biomedical sensor. It has been designed as an implantable sensor where all the connections are
on one side. The bonding pads are large in order to glue or solder wires on.
The sensor element of the MS763 consists of a silicon micro-machined membrane. Implanted resistors sense
the deformation of the membrane by using of the piezo-resistive effect. The MS763 is available as a differential
sensor (MS763-S) without base Pyrex or as an absolute sensor with a 0.2 mm thick Pyrex (MS763-A).
