MMA6260QR2 Overview
What is an accelerometer? An accelerometer is a micro-electromechanical (MEMS) sensor that measures proper acceleration along one or more axes and converts that physical displacement into an analog voltage or digital signal. In the broader sensor taxonomy, the MMA6260QR2 sits at: MEMS accelerometer → inertial sensor → motion sensor → semiconductor IC. It is used wherever a system needs to detect tilt, vibration, shock, or orientation in a compact, low-power surface-mount form factor.
Key features include ±1.5g full-scale range on both axes, fully conditioned analog outputs, integrated temperature compensation, factory-trimmed zero-g offset and sensitivity, self-test capability, and a 1-pole low-pass analog filter with the cutoff factory-set to eliminate external RC components. The 16-QFN-EP package provides a thermal pad for stable operation across the -40 °C to +85 °C industrial range.
Technically, the device uses a capacitive MEMS proof-mass structure whose differential capacitance changes with acceleration; on-chip CMOS ASIC converts this to a ratiometric analog voltage. Two g-select pins allow the user to command four sensitivity options (±1.5g / ±2g / ±4g / ±6g) by setting logic levels, and a logic-high on the self-test pin applies an electrostatic force to the proof mass for end-of-line verification.
Typical applications include automotive airbag deployment detection, tilt and orientation sensing in consumer electronics, industrial vibration monitoring, gaming controllers, and HDD free-fall detection. The small 6x6 mm QFN package suits space-constrained PCB layouts.
When designing with this part, place the device near the edge of the PCB where the mechanical stress is low, follow NXP's recommended footprint exactly, and tie unused outputs to ground through a high-impedance buffer to prevent crosstalk.

Typical Applications
MMA6260QR2 is suitable for 6 applications: Automotive Airbag Deployment Sensing, Tilt and Orientation Sensing in Consumer Electronics, Industrial Vibration Monitoring, Gaming Controller Motion Input, HDD Free-Fall Detection, Security and Surveillance Camera Tilt Detection.
Automotive Airbag Deployment Sensing
The MMA6260QR2's ±1.5 g range on the X and Y axes is well-suited to early-stage crash detection where chassis deceleration must be monitored before higher-g events propagate. Its on-chip temperature compensation and factory-trimmed offset (per NXP datasheet) help suppress false triggers across -40 °C to +85 °C underhood conditions, while the exposed-pad 16-QFN-EP package dissipates self-heating during long ignition-on dwells. Compared with a discrete accelerometer + op-amp chain, the integrated 1-pole 50 Hz filter cuts BOM cost and eliminates hand-tuned RC networks on each axis. Engineering note: always pair the part with a redundant sensor in safety-critical airbag paths; the MMA6260QR2 alone does not meet ASIL requirements.
Recommended
Tilt and Orientation Sensing in Consumer Electronics
The MMA6260QR2's dual-axis X/Y output lets handheld devices detect screen-rotation tilt events by measuring gravity components along the plane of the display. The analog ratiometric output drives an ADC channel directly, simplifying the interface versus digital I²C accelerometers that need a host MCU driver. Bandwidth of 50 Hz is fast enough for shake-to-shuffle gestures but filters out hand tremor above 10 Hz, reducing software debounce burden. The 6x6 mm QFN-EP footprint sits beneath the screen flex area without intruding into the antenna keep-out zone.
Recommended
Industrial Vibration Monitoring
Pump, motor, and bearing health monitoring depends on low-frequency vibration signatures typically below 200 Hz, where the MMA6260QR2's 50 Hz analog filter rejects high-frequency motor switching noise and supplies a clean envelope. Its X/Y axis pair captures both radial and axial vibrations on rotating shafts when mounted with the die surface facing the housing. The factory-trimmed zero-g offset and sensitivity (per NXP datasheet) keep calibration drift under 1 % across the industrial -40 °C to +85 °C window, supporting unattended predictive-maintenance deployments. Tie unused outputs through a high-Z buffer to prevent crosstalk with adjacent ADC channels.
Recommended
Gaming Controller Motion Input
Wireless gamepads and motion controllers demand low-latency tilt feedback at low g-forces, exactly the regime where the MMA6260QR2's ±1.5 g dual-axis analog output excels. With a 50 Hz internal filter it rejects accelerometer self-noise above the gesture band, giving the MCU a clean signal for gesture recognition without oversampling burden. The 16-QFN-EP (6x6 mm) is small enough to fit alongside Bluetooth SoCs in the cramped controller enclosure, and the exposed pad ties to chassis ground for EMI shielding. Pair with a host-side digital filter to push effective bandwidth higher if needed.
Recommended
HDD Free-Fall Detection
Hard-disk-drop detection requires a fast, low-g-axis response that triggers a heads-park command within milliseconds of the laptop falling. The MMA6260QR2's low-g X/Y axes detect initial gravity-vector tilt changes well before impact, giving the disk controller an early warning window. The 50 Hz analog filter is broad enough for typical 0.5-2 m drop durations, and the ratiometric output couples directly to the drive controller's analog comparator inputs. Pair with a Z-axis sensor (e.g., MMA6233Q) for complete 3-axis coverage in storage products.
Recommended
Security and Surveillance Camera Tilt Detection
Outdoor security cameras mounted on poles are vulnerable to tampering and wind-induced sway, both of which the MMA6260QR2 can detect via X/Y axis tilt changes. The ±1.5 g range fits the typical 90° tilt envelope of a knocked-over fixture without saturating the analog output. The exposed-pad QFN-EP dissipates heat under continuous solar load and provides mechanical rigidity for outdoor enclosures. Feed the XOUT/YOUT lines into a low-power MCU that wakes the camera or alerts the central station when tilt exceeds a programmable threshold.

Design Notes
Mount the MMA6260QR2 with the silicon die on the underside of the package, near the edge of the PCB where bending strain from board flexure is minimized. The exposed pad must be soldered to the PCB ground plane via at least 9 thermal vias in a 3x3 array to maximize heat extraction per NXP application guidance. Avoid placing the part directly over PCB cutouts or screw holes where mechanical stress could feed back into the MEMS structure and bias the offset.
Decouple the VDD pin with a 0.1 µF X7R ceramic capacitor placed within 3 mm of the device pin. The analog outputs are ratiometric, so any ripple on VDD couples directly into XOUT/YOUT as measurement noise. For best low-g sensitivity, add a 10 µF bulk capacitor at the regulator output and consider a ferrite bead between the analog and digital supply rails to isolate switching noise.
Route the XOUT and YOUT traces as 50 Ω controlled-impedance microstrip if they exceed 25 mm, and place a series 100 Ω resistor near the sensor pin to damp the first-order LC resonance of the trace with the ADC input capacitance. Guard the analog traces with a ground pour on both sides, and never cross them over digital clock lines; even 50 mV of digital noise can swamp the few-mV tilt signal at the output.
Do not assume the g-select pins default to the ±1.5 g range on every MMA62xx family variant - several parts require explicit logic levels to be set within 100 ms of power-up. Also, the self-test pin must be driven low during normal operation; leaving it floating can cause undefined output behavior and reduce measurement accuracy by up to 5 %.
Compliance Information
Lead status 'Contains Lead' is from the older Digchip listing; the RoHS compliance entry likely reflects a later conversion by NXP. AEC-Q100 not explicitly stated in the datasheet excerpt. Verify with the latest NXP PCN before automotive use.
