Manufacturer Part Number

ADXL337BCPZ

Description

The ADXL337BCPZ is a compact, analog-output, three-axis accelerometer. It measures acceleration in the X, Y, and Z axes, with a ±3g sensing range. Designed for simple integration, it outputs analog voltage signals proportional to acceleration. This helps detect movement, tilt, and orientation changes in electronic devices. The device comes in a tiny 16-lead LFCSP package for easy placement on PCBs.

Device Structure

16-lead LFCSP (Lead Frame Chip Scale Package)

Solid-state MEMS motion sensor with three axis detection

Compact form factor, suitable for modern, high-density circuit boards

Performance Characteristics

Accurately measures acceleration up to ±3g on each axis

Low power consumption, ideal for small, battery-operated devices

Stable analog output with low noise

Consistent sensitivity over full supply range

Very small package allows use in compact designs

Application Environments

Consumer electronics (smartphones, tablets)

Robotics and drones for orientation and movement detection

Handheld measurement instruments

Wearable devices

Portable data loggers

Gaming devices and controllers

Alarm and security systems for motion detection

Selection Guidelines

Choose for applications needing simple, direct analog outputs for X, Y, Z acceleration

Ideal where compact PCB area or shape is critical

Check that ±3g range is suitable for your motion limits

Confirm analog signal processing capability in your system

Ensure moisture control in packaging and handling because of MSL 3

Usage Considerations

Obsolete part: plan for eventual phase-out or design migration

Analog output: requires clean signal paths and ADCs in system

Moisture Sensitive: must be soldered and handled within 168 hours after opening packaging

Avoid high mechanical stress during PCB assembly

May require calibration to account for system-level offset or bias

Potential Equivalent/Replacement Models

Yes, there are possible equivalent or alternative models. The manufacturer specifies ADXL335BCPZ as a direct substitute.

Other Analog Devices’ accelerometer models in similar package and output format may work, but check pinout, sensitivity range, and supply voltage for each option.
