General Description 一般描述
The SMD085 is a high precision barometric pressure sensor.
The measurement principle is based on a piezoresistive
technology with a very robust design and high accuracy. It is
packaged in a SMD08 housing. The main application is ambient
pressure measurement.
The SMD085 consists of an integrated sensing element, a logic
control unit, a temperature compensation circuit as well as an
offset compensation circuit. The output voltage is between
2.37 V and 4.54 V for a pressure range between 60 kPa and
115 kPa.
Due to the full integrated concept, no additional external circuits
are necessary. The bipolar technology of the integrated signal
condition circuit guarantees a high ESD protection. The output
circuit is protected against short circuiting to VDD and GND.
