MMR906

This gauge pressure sensor is a pressure sensor IC utilizing MEMS technology. It combines a MEMS sensor with a Delta-Sigma (⊿Σ) AD converter to output high-precision pressure values digitally. I2C and SPI interfaces are available.

Outline

This product digitally outputs a pressure value which was corrected. Customers need no correction because it corrects and outputs the differences of sensors and temperature characteristics. It does not require complicated sensor drive or control circuit, and devices with high performance can be made only with this module and an external microcontroller which will be the host.
