The MMA6270Q is a low cost, low power, dual axis, low-g micromachined accelerometer from Freescale Semiconductor that features signal conditioning, a 1-pole low pass filter, temperature compensation and g-Select which allows for the selection among four sensitivities. Zero-g offset full scale span and filter cut-off are factory set and require no external devices.
The MMA6270Q is a surface‑micromachined dual‑axis accelerometer that includes on‑chip signal conditioning, a low‑pass filter, temperature compensation, and a g‑Select feature for four sensitivity settings (1.5 g, 2 g, 4 g, 6 g). It operates from 0.3 V to 3.6 V, draws as little as 500 pA in active mode and 3 pA in sleep mode, and is packaged in a 6 mm × 6 mm × 1.45 mm QFN‑16.
Typical applications include free‑fall detection in laptops, motion sensing for robotics, vibration monitoring in appliances, and tilt‑compensated e‑compass functions in handheld devices. Ordering information and pin‑out details are provided for both tape‑and‑reel and tube packaging.
