The MMA7330L is a low power, low profile capacitive micromachined accelerometer featuring signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and g-Select which allows for the selection between 2 sensitivities. Zero-g offset and sensitivity are factory set and require no external devices. The MMA7330L includes a Sleep Mode that makes it ideal for handheld battery powered electronics.
The MMA7330L is a low‑power, low‑profile capacitive MEMS accelerometer with built‑in signal conditioning, a 1‑pole low‑pass filter, temperature compensation, self‑test, and selectable 4 g or 12 g sensitivity. It operates from 2.2 V to 3.6 V, draws as little as 400 pA in active mode and 3 pA in sleep mode, and is RoHS‑compliant, making it suitable for handheld, battery‑powered devices.
The device is supplied in a 14‑lead LGA package (3 mm × 5 mm × 1.0 mm) and offers a maximum acceleration rating of +5000 g. Key electrical specifications include a supply voltage range of 2.2 V‑3.6 V, typical supply current of 400 pA, sleep‑mode current of 3 pA, 4 g sensitivity of 308 mV/g, 12 g sensitivity of 83.6 mV/g, bandwidth up to 400 Hz on X/Y axes, and an output impedance of 32 kΩ. Typical applications cover gaming, free‑fall detection, anti‑theft, motion sensing for robotics, and navigation.
| Package | 3 mm × 5 mm × 1.0 mm LGA‑14 |
|---|---|
| Supply Current (typical) | 400 pA |
