The SM99A is a silicon micro-machined, piezoresistive pressure-sensing chip. The SM99A is designed for harsh media where absolute pressure needs to be accurately measured. In contrast to traditional pressure-sensing chips the media only comes in contact with silicon materials. Therefore, the electronic structures on the front side of the die will not be affected during operation. This results in a durable pressure sensor suitable for challenging applications. The family will be qualified using AEC-Q100 Level 0 Automotive standards. An on-board temperature diode is provided for point-of-use temperature sensing.
Samples are available in a full-scale range of 1 Bar, 4 Bar and 8 Bar absolute (14.5, 58 and 116 PSIA) and is 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.
