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.
SMD085 是一个高精度的大气压力传感器。测量原则根据压阻技术以一个非常健壮设计和高精确度，主要应用在空气测量。逻辑控制单元， 一条温度补偿电路并且一条垂距报偿电路。
