ADXL320JCP - Analog Devices Inc.

The ADXL320JCP is a small, thin, low-power, complete 3-axis accelerometer with signal conditioned voltage outputs, all on a single monolithic IC. Manufactured by Analog Devices Inc., a renowned leader in precision signal processing, the ADXL320JCP is designed to measure acceleration with a full-scale range of ±5g. It can measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion, shock, or vibration.

This high-performance product features a typical nonlinearity of 0.3% of full-scale range, and a 1 mg/√Hz typical noise floor, allowing signals below 5 mg to be resolved in tilt-sensing applications using narrow bandwidths. The ADXL320JCP is widely used in vehicle dynamic controls, electronic stability programs, and rollover detection in automobiles. It is also suitable for a variety of other applications, including industrial and instrumentation devices, platform stabilization/antenna alignment, and sports and health devices.

The accelerometer is temperature-stable and calibrated over the temperature range to ensure minimal performance variation. It operates from a single 5 V power supply, and is available in a compact, 5 mm × 5 mm × 2 mm, 16-lead, plastic LFCSP package.

Key features of the ADXL320JCP include:

• 3-axis sensing
• Low power consumption: 700 µA at 5 V (typical)
• Full-scale range: ±5 g
• Sensitive to low-frequency motion
• High signal-to-noise ratio
• Excellent temperature stability
• Self-test feature
• RoHS/WEEE lead-free compliant

For ease of use, this accelerometer is available with analog outputs that can be directly interfaced with a range of microcontrollers, analog-to-digital converters (ADCs), or embedded processors, eliminating the need for additional signal conditioning. The robust design of the ADXL320JCP, along with its ability to operate over extended temperatures, makes it a reliable choice for demanding environments and applications.

When precision motion sensing is critical, the ADXL320JCP from Analog Devices Inc. offers a dependable and versatile solution for a wide array of applications.
