Low-profile three-axis low-g digital-output accelerometer
Available now from RS Components, the Freescale MMA7455L is a digital-output
(I2C/SPI) low-power low-profile capacitive micro-machined accelerometer.
The device features signal conditioning, a low pass filter, temperature
compensation, self-test, configurable to detect 0g through interrupt pins
(INT1 or INT2), and pulse detect for quick motion detection.
The 0g offset and sensitivity are factory set and require no external
devices. The 0g offset can be user calibrated using assigned 0g registers
and g-Select which allows for command selection for three acceleration
ranges (2g/4g/8g). The MMA7455L includes a Standby Mode that makes it ideal
for handheld battery-powered electronics.
