Technical Data
±1.5g - 6g Three Axis Low-g
Micromachined Accelerometer
The MMA7260Q low cost capacitive micromachined accelerometer
features signal conditioning, a 1-pole low pass filter, temperature
compensation and g-Select which allows for the selection among 4
sensitivities. Zero-g offset full scale span and filter cut-off are factory set and
require no external devices. Includes a Sleep Mode that makes it ideal for
handheld battery powered electronics.

1. For a loaded output, the measurements are observed after an RC filter consisting of a 1.0 kΩ resistor and a 0.1 µF capacitor to ground.
2. These limits define the range of operation for which the part will meet specification.
3. Within the supply range of 2.2 and 3.6 V, the device operates as a fully calibrated linear accelerometer. Beyond these supply limits the device
may operate as a linear device but is not guaranteed to be in calibration.
4. This value is measured with g-Select in 1.5g mode.
5. The device can measure both + and – acceleration. With no input acceleration the output is at midsupply. For positive acceleration the output
will increase above VDD/2. For negative acceleration, the output will decrease below VDD/2.
6. The response time between 10% of full scale Vdd input voltage and 90% of the final operating output voltage.
7. The response time between 10% of full scale Sleep Mode input voltage and 90% of the final operating output voltage.
8. A measure of the device’s ability to reject an acceleration applied 90° from the true axis of sensitivity.
