Analog Devices Inc. ADXL345TCCZ-EP

The ADXL345TCCZ-EP is an extended performance version of the ADXL345, a small, thin, ultralow power, 3-axis accelerometer produced by Analog Devices Inc. This device is designed for high-resolution (13-bit) measurement at up to ±16 g and is particularly suited for extended temperature range industrial and aerospace applications. It measures both static acceleration of gravity in tilt-sensing applications and dynamic acceleration resulting from motion or shock. The ADXL345TCCZ-EP is supplied in a 3 mm × 5 mm × 1 mm, 14-lead, enhanced plastic package (LGA).

• High Resolution Measurement: Up to 13-bit resolution at ±16 g, enabling measurements of inclination changes less than 1.0°.
• Special Sensing Functions: Activity and inactivity sensing, tap sensing (single and double taps), and free-fall sensing. These functions can be mapped individually to either of two interrupt output pins.
• Integrated Memory Management: A 32-level first in, first out (FIFO) buffer to store data, minimizing host processor activity and lowering overall system power consumption.
• Low Power Modes: Intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.
• Digital Interfaces: SPI (3- or 4-wire) and I2C interfaces for flexible communication.
• Extended Temperature Range: Operating temperature range of −55°C to +105°C, making it suitable for industrial and aerospace applications.
• Compact Package: Supplied in a small, thin, 3 mm × 5 mm × 1 mm, 14-lead LGA package.

• Industrial Equipment: Suitable for various industrial applications due to its extended temperature range and robust design.
• Aerospace Equipment: Compliant with AQEC standards, making it suitable for defense and aerospace applications.
• Medical Instrumentation: Can be used in medical devices requiring precise motion sensing.
• Gaming and Pointing Devices: Ideal for gaming controllers and other pointing devices that require accurate motion detection.
• Personal Navigation Devices: Used in GPS and other navigation devices to enhance location accuracy.
• Hard Disk Drive (HDD) Protection: Helps in protecting HDDs from shocks and drops).
