MMA2260DR2 - ±1.5g X-Axis Micromachined Accelerometer | NXP
MPN: MMA2260DR2 ⚠ آخرین فرصت خریدMMA2260DR2 نمای کلی
An accelerometer is a MEMS (micro-electro-mechanical systems) sensor that detects linear acceleration along one or more axes. The capacitive micromachined topology used in the MMA2260DR2 measures acceleration-induced proof-mass displacement via differential capacitance change, then conditions the signal through on-chip CMOS electronics. In the broader sensor hierarchy, the MMA2260DR2 sits as: accelerometer -> inertial sensor -> motion sensor -> MEMS device -> semiconductor IC. This category provides orientation, vibration, tilt, and shock information used for safety, control, and user-interface functions.
Key features of the MMA2260DR2 include a ratiometric analog output (sensitivity scales with supply), a self-test pin for built-in diagnostics, on-chip temperature compensation, and a rugged SOIC-16 housing tolerant of the harsh environments typical of automotive and industrial applications. The integrated 2-pole low-pass filter limits aliasing and out-of-band mechanical noise. Because zero-g and span are factory trimmed, designers drop the sensor onto a PCB with no external calibration components beyond the supply bypass capacitor.
The MMA2260DR2's mixed-signal CMOS signal conditioning chain converts the capacitive sensor signal to a low-impedance analog output voltage, while on-chip temperature compensation holds zero-g offset and sensitivity across the industrial temperature range. The 50 Hz filter corner is well below typical automotive and machine-vibration spectra to keep high-frequency mechanical noise out of downstream ADCs. This analog-output architecture fits legacy 0-5V system designs and avoids the digital I2C/SPI overhead that newer parts such as the MMA845x family require.
Typical applications for the MMA2260DR2 include automotive airbag restraint systems, anti-lock brake (ABS) sensors, security motion detection, inclinometers, vibration monitoring in industrial equipment, and tilt/proximity detection in appliances. The ±1.5g range suits low-g instrumentation rather than crash-event sensing. Designers select the ratiometric analog interface when integration with a traditional 0-5V ADC and microcontroller without I2C is needed.
When designing with the MMA2260DR2, add a 0.1 microfarad bypass capacitor close to the supply pin and a small RC network on the output for EMI suppression when routed near motor or ignition cabling. Avoid mechanical stress on the package, as PCB flex can shift offset beyond the factory trim. The analog output swings roughly 0.5V to 4.5V on a 5V supply; saturating into the rails reduces usable resolution at the highest g ranges.

کاربردهای معمول
MMA2260DR2 مناسب است برای 6 کاربردs: Automotive Airbag Crash Sensor (legacy restraint module), Inclinometer / Tilt Sensor, Industrial Vibration Monitoring, Security / Motion Detection, Anti-Lock Brake System (ABS) Wheel-Speed Sensor Interface (legacy), Consumer Appliance Tilt Sensing.
Automotive Airbag Crash Sensor (legacy restraint module)
The MMA2260DR2's ±1.5 g X-axis range and 50 Hz low-pass filter suit slow-tilt and roll sensing channels inside legacy restraint modules. Its ratiometric analog output drives 0-5 V system ADCs without digital I2C overhead, and the on-chip temperature compensation holds zero-g offset across -40 C to +85 C underhood swings. Use the self-test pin to verify sensor health at airbag ECU power-up; the wide SOIC-16 package survives automotive mechanical stress.
پیشنهادی
Inclinometer / Tilt Sensor
With its narrow ±1.5 g range and factory-trimmed zero-g offset, the MMA2260DR2 makes a low-cost analog tilt sensor for construction levels, agricultural equipment, and HVAC vent position feedback. At 0 deg horizontal the output sits near mid-scale (2.5 V at 5 V supply), and at 90 deg vertical it rises to roughly 4.5 V. The 50 Hz internal filter rejects motor vibration on heavy equipment platforms.
پیشنهادی
Industrial Vibration Monitoring
The 50 Hz internal 2-pole low-pass filter and the analog-output interface of the MMA2260DR2 suit FFT-style machine-condition monitoring on pumps, fans, and motor housings. Mount the SOIC-16 housing flat against the equipment chassis and route the ratiometric output to a 12-bit ADC running at 1 kHz. The ±1.5 g range maps vibration amplitude on rotating machinery without saturating on startup transients.
پیشنهادی
Security / Motion Detection
The MMA2260DR2's X-axis analog output integrates cleanly with PIR-augmented intrusion panels: the self-test pin verifies the sensor at startup, and the 50 Hz bandwidth filters out sub-Hz thermal noise and high-frequency switching transients. Its ratiometric output swings 0.5-4.5 V, so a window comparator triggers an alarm when the panel is moved or tilted. The wide SOIC-16 footprint survives rough handling during installation.
پیشنهادی
Anti-Lock Brake System (ABS) Wheel-Speed Sensor Interface (legacy)
Legacy ABS ECUs use single-axis low-g analog accelerometers such as the MMA2260DR2 to detect vehicle deceleration and wheel-lock events. Its ratiometric output drives the ECU's 5 V ADC directly without digital interface glue, and the on-chip temperature compensation maintains offset across underhood thermal swings. Designers should add a 0.1 microfarad bypass capacitor close to the supply pin for stable readings.
پیشنهادی
Consumer Appliance Tilt Sensing
Washing machines, robotic vacuums, and mobile appliances use single-axis low-g accelerometers such as the MMA2260DR2 to detect unbalanced loads or fall events. The factory-trimmed zero-g offset simplifies the load-balance algorithm and removes the need for in-line calibration. The analog output feeds directly into the appliance MCU's ADC, leaving I2C bus bandwidth free for other sensors.

یادداشت‌های طراحی
Place a 0.1 microfarad ceramic bypass capacitor within 5 mm of the VCC pin (pin 3) to suppress supply noise. Mechanical stress on the SOIC package can shift zero-g offset, so mount the accelerometer near board anchor points rather than in cantilevered sections. Reference the NXP AN1667 MEMS application note for layout practices.
The MMA2260DR2's analog output is ratiometric to VCC: any regulator drift on the 5 V supply directly couples into the acceleration reading. Use a low-dropout regulator with 1 percent or better tolerance and add a ferrite bead on the supply rail if the sensor sits near switching converters. Saturation into the 0.5 V or 4.5 V rails reduces usable resolution at the maximum g range.
Route the analog VOUT trace away from motor phases, ignition cables, and high-current switching traces. Add a 100 ohm series resistor plus 1 nF to 10 nF capacitive load at the input of the downstream ADC to form a low-pass anti-aliasing filter. The internal 50 Hz filter corner only protects against mechanical noise, not EMI picked up on long PCB traces.
