SILICON MICROSTRUCTURES INCORPORATED
* OEM SILICON PRESSURE SENSOR DIE
SM5102
OEM Silicon Pressure Die
DESCRIPTION
The SM5102 is a silicon micro-machined, piezoresistive pressure-sensing chip. These devices are available in full-scale ranges from 5 to 300 psi and are ideal for OEM and high volume applications. Provided in die form, these sensors can be mounted on ceramic or PC board substrates as part of an OEM system. They also may be packaged into proprietary, or application specific sensor lines. Die are probed, inked and diced, and shipped on tape. Custom pressure ranges available in highvolume applications. Field-shield, high stability parts are also available on a custom-bases.
Compensated

Notes: 1. Bridge may be driven with positive or negative voltage as long as Vsub is not connected. Positive output for positive pressure applied to circuit side of die when bridge is driven with positive voltage. 2. Measured at 5V constant voltage excitation. 3. Measured from 0 to 70 C 4. Defined as best straight line.
