MS7904 - PRESSURE SENSOR DIE

General Description

The sensor element of the MS7904 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.

Key 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 (MS7904-A).
Low cost, high reliability.

MS7904 PRESSURE SENSOR DIE (0-4 BAR) • 0 to 400 kPa range (4 bar or 58 PSI) • Absolute/differential pressure sensors • High linearity, small size • High overpressure capability (15 bar) • RoHS-compatible & Pb-free1 DESCRIPTION The sensor element of the MS7904 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 (MS7904-A_0.2) or 0.5 mm (MS7904-A_0.5).
