PBM210 series
The PBM210 is a new generation of high resolution digital barometer. The PBM210 is a
digital pressure sensor which consists of a MEMS piezoresistive pressure sensor and a signal
conditioning ASIC. The ASIC include a 24bits sigma-delta ADC, OTP memory for calibration data, and serial interface circuits. The PBM210 could provide both I2C and SPI interface to communicate with microcontroller. Pressure calibrated and temperature compensated were key features of the PBM210. The data stored in OTP memory could be used to calibrate the PBM210. The calibration procedure should be implemented by an external microprocessor. The PBM210 is low power and supply voltage designed and suitable for portable devices or battery-supplied ones.
