Replacement: None. We are no longer carrying this Triple-Axis Accelerometer in our catalog. This page is for reference only.

Description: The MMA7361LR1 is a low power, three-axis analog MEMS accelerometer. The sensor has a g-Select input which allows for the selection between two measuring ranges - ±1.5g or ±6g.

Other features include signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and 0g-detect which detects linear freefall. Zero-g offset and sensitivity are factory set and require no external devices. The MMA7361L also includes a sleep mode.

The sensor works on power between 2.2 and 3.6VDC (3.3V optimal), and typically consumes just 400µA of current. All three axes have their own analog output.

Features:

  • Two selectable measuring ranges (±1.5g, ±6g)
  • Low current consumption: 400 µA
  • Sleep mode: 3 µA
  • Low voltage operation: 2.2 V - 3.6 V
  • High sensitivity (800 mV/g at 1.5g)
  • Fast turn on time (0.5 ms enable response time)
  • Self test for freefall detect diagnosis
  • 0g-Detect for freefall protection
  • Signal conditioning with low pass filter
  • Robust design, high shocks survivability
  • RoHS compliant
  • Environmentally preferred product
  • Low cost

Dimensions: 3.0 x 5.0 x 1.0 mm (LGA-14-pin package)

  • Hey…. Can i solder this on PCB?? and at which temperature???

    • If you’re careful, you can solder it by hand, at standard temperatures. (Like any other part, you can avoid overheating it by soldering one lead at a time and letting it cool a bit between).

      You might also consider purchasing it already mounted on a breakout board (in the related products below), and mounting the breakout to your PCB, which would be an easier soldering job.

      • Thank You!!! Yaa…. I know about breakout board..but actually the matter is i have 2 acce. of this type!! In future, i will purchase breakout only… and i asked this because product can sustain upto 70C or 80C only..and normal soldering temp. is about 200*C!! So….

  • Guys,
    I can not make it work properly.
    In 6g configuration, it seems the temperature compensation does not do its job, and simply when I blow on it, the output drops from 2000lsb (12 bits ADC) to 1800lsbn which is 10% or nearly 1g !
    In the spec, it is written 0.5mg/?C biais stability.
    Clearly I never saw this.
    However, mechanic stress does not affect the output, which is good news.
    Has anybody been able to make it work properly ?
    Antoine

  • Any update on the breakout board?
    Thx

  • Hi
    When is the promised breakout board coming?
    Cheers.
