BMP180 DIGITAL PRESSURE SENSOR BMP180 general description The BMP180 is the function compatible successor of the BMP085, a new generation of high precision digital pressure sensors for consumer applications. The ultra-low power, low voltage electronics of the BMP180 is optimized for use in mobile phones, PDAs, GPS navigation devices and outdoor equipment. With a low altitude noise of merely 0.25m at fast conversion time, the BMP180 offers superior performance. The I2C interface allows for easy system integration with a microcontroller. The BMP180 is based on piezo-resistive technology for EMC robustness, high accuracy and linearity as well as long term stability. Key features: Pressure range: 300 ... 1100hPa (+9000m ... -500m relating to sea level) Supply voltage: 1.8 ... 3.6V (VDD) 1.62V ... 3.6V (VDDIO) Package: LGA package with metal lid Small footprint: 3.6mm x 3.8mm Super-flat: 0.93mm height Low power: 5µA at 1 sample / sec. in standard mode Low noise: 0.06hPa (0.5m) in ultra low power mode 0.02hPa (0.17m) advanced resolution mode Temperature measurement included I2C interface Fully calibrated Pb-free, halogen-free and RoHS compliant, MSL 1 Typical applications Enhancement of GPS navigation (dead-reckoning, slope detection, etc.) In- and out-door navigation Leisure and sports Weather forecast Vertical velocity indication (rise/sink speed)
