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.
Applications
Blood pressure monitor for home appliance
Devices using air pressure
Features
① Small package 7.0(W) ×7.0(D) ×7.2(H)mm
② A high-accuracy pressure value can be output
by mounting a ⊿Σ AD converter.
Resolution: 3.3 Pa (0.025 mmHg)
Accuracy: ± 266 Pa (±2 mmHg)
③ Temperature compensation can be performed
by using the incorporated temperature sensor
and the compensation data in EEPROM.
* No arithmetic function is built in.
