... The peak-to-peak noise is approximately equal to 6.6 times the rms value (for an average uncertainty of 0.1%). DIGITAL INTERFACE The MXD2020G/H/M/N is easily interfaced with low cost microcontrollers. For the digital output accelerometer, one digital input port is required to read one accelerometer output. For the analog output accelerometer, many low cost ...
