Описание
ADXL345 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13bit) measurement at up to ±16 g. Digital output data is formatted as 16bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. It is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (3.9mg/LSB) enables measurement of inclination changes less than 1.0°. Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds. Tap sensing detects single and double taps in any direction. Free-fall sensing detects if the device is falling. Typical applications are handsets, medical instrumentation, gaming and pointing devices, industrial instrumentation, personal navigation devices, hard disk drive (HDD) protection.
• Ultralow power is as low as 23µA in measurement mode and 0.1µA in standby mode at VS=2.5V (typ)
• Power consumption scales automatically with bandwidth, user-selectable resolution
• Embedded memory management system with FIFO technology minimizes host processor load
• Single tap/double tap detection, activity/inactivity monitoring, free-fall detection
• Flexible interrupt modes mappable to either interrupt pin, bandwidth selectable via serial command
• Measurement ranges selectable via serial command, 10000g shock survival
• Operating voltage range from 2 to 3.6V (TA=25°C, VS=2.5V, VDD I/O=1.8V)
• Supply current is 140µA (ODR >= 100Hz, TA=25°C, VS=2.5V, VDD I/O=1.8V)
• 14-lead LGA package
• Temperature rating range from -40°C to +85°C
