7260QR2
Freescale Semiconductor
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.
Features
• Selectable Sensitivity (1.5g/2g/4g/6g)
• Low Current Consumption: 500 µA
• Sleep Mode: 3 µA
• Low Voltage Operation: 2.2 V – 3.6 V
• 6mm x 6mm x 1.45mm QFN
• High Sensitivity (800 mV/g @1.5 g)
• Fast Turn On Time
• High Sensitivity (1.5 g)
• Integral Signal Conditioning with Low Pass Filter
• Robust Design, High Shocks Survivability
• Pb-Free Terminations
• Environmentally Preferred Package
• Low Cost
Typical Applications
• HDD MP3 Player : Freefall Detection
• Laptop PC : Freefall Detection, Anti-Theft
• Cell Phone : Image Stability, Text Scroll, Motion Dialing, E-Compass

ELECTRO STATIC DISCHARGE (ESD)
WARNING: This device is sensitive to electrostatic
discharge.
Although the Freescale accelerometer contains internal
2000 V ESD protection circuitry, extra precaution must be
taken by the user to protect the chip from ESD. A charge of
over 2000 volts can accumulate on the human body or
associated test equipment. A charge of this magnitude can
alter the performance or cause failure of the chip. When
handling the accelerometer, proper ESD precautions should
be followed to avoid exposing the device to discharges which
may be detrimental to its performance.
