Measurement Specialties (formerly Intersema)
These devices contain a pressure sensor and an interface IC with digital output. The devices are electrically trimmed at factory and optimized to interface to Low Power battery supplied microcontrollers. Highest accuracy of < 0.5% is achieved with a current consumption of just a few microamperes. Typical applications are high resolution watch altimeters, barometers, navigation instruments, etc...
Various pressure ranges from 100 mbar (10 KPa) up to 14 bars (1400 KPa) are offered.
Surface mounted device (SMD) devices are pressure sensors mounted and bonded on a ceramic substrate. These small size devices can then easily be mounted on a standard printed board. Uncompensated SMD sensors require external amplification and temperature compensation. The output signal in the range of 90 to 240 mV with a linearity of 0.05% to 0.5% is depending on the type.
Pressure Sensor Dice Uncompensated (Pb-free & RoHS-compatible): Pressure sensors can be delivered as dice, for very small embedded applications. The sensor can even be integrated into another device. Dice are usually delivered as tested sensor on a sawn wafer on blue foil (mylar type). The pressure range offered is from 100mbar (10KPa) up to 14bars (1400 KPa), Die sizes range from 1.48 x 1.62 mm to 2.5 x 2.5 mm. Typical applications are cost critical high volume OEM products.
