ADI samples analog 3-axis, high-g MEMS accelerometer

Analog Devices Inc. (ADI) has started to sample what it claims is the industry's first commercially available analog, 3-axis, high-g MEMS accelerometer.

The ADXL377 measures acceleration of high-impact events resulting from shock and vibration, within the full-scale range of ±200 g with no signal saturation. This measurement range, combined with an analog output that continuously captures impact data, make the ADXL377 well-suited for contact sports where the detection of concussive forces can reveal indictors of Traumatic Brain Injury (TBI).

With a bandwidth of 1600Hz, the ADXL377 is also suitable in industrial equipment where shock levels must be closely monitored. ADI's new 3-axis accelerometer also eliminates the need for alignment and the placement of orthogonal sensors, which significantly simplifies design. The board space requirement is reduced by up to five times that of typical solutions requiring multiple, single-axis accelerometers, according to ADI.

Key highlights:

• 3-axis sensing
• Range (g): ±200
• Power consumption: 300 μA (typical)
• Single-supply operation: 1.8 V to 3.6 V
• 10,000 g shock survival
• Small and thin package
• Bandwidth: 1600 Hz is suited for industrial impact detection applications

• 3 mm × 3 mm × 1.45 mm 16-lead LFCSP
