MMA7340L - Three Axis Low-g Micromachined Accelerometer

General Description

Sleep Mode The 3 axis accelerometer provides a Sleep Mode that is ideal for battery operated products.

When Sleep Mode is active, the device outputs are turned off, providing significant reduction of operating current.

Key Features

  • 3mm x 5mm x 1.0mm LGA-14 Package Low Current Consumption: 400 µA Sleep Mode: 3 µA Low Voltage Operation: 2.2 V.
  • 3.6 V Selectable Sensitivity (±3g, ±12g) 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.
