MMR901

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 is a small piezoresistive pressure sensor using MEMS technology. The product mounts a ⊿Σ AD converter with a resolution of 16 bits and outputs a high-accuracy pressure value as a digital value. SPI is adopted for the interface and communication is performed with a microcomputer. When an incorporated temperature sensor and EEPROM data are used, a characteristic change due to a temperature change can be compensated by the dedicated software on an external microcomputer.
