MS79005
PRESSURE SENSOR DIE (0-0.5 BAR)
0 to 50 kPa range (500 mbar or 7.5 PSI)
Absolute/differential pressure sensors
RoHS-compatible & Pb-free1
DESCRIPTION
The sensor element of the MS79005 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 (MS79005-A_0.2) or 0.5 mm (MS79005-A_0.5). Two gauge
versions available: one with a drilled Pyrex glass (MS79005-D) and the other without Pyrex glass (MS79005-S).
FEATURES
Uncompensated pressure sensor die
Output Span 150mV @ 5V

Important remarks:
As the sensing elements are diffused resistances, the voltage
applied on the ground pads (GND1 and GND2) has to be lower
than the voltage applied on supply voltage pad (Vs+).
The epitaxial layer is connected to the Vs+ pin under the pad.
Gold ball bonding or aluminium wedge bonding can be used to
wire-bond the sensor. The quality of the wire-bonding is equipment
and process dependant. For this reason, it is strongly
recommended that a thorough wire-bonding qualification is made
by the end user if the sensor is going to be operated over an
extended temperature range.
