Data Sheet MX205Q Page 1 of 8 MX205Q (RATIOMETRIC) Low Cost, 5.0g, Dual Axis Accelerometer with Analog Outputs General Description The MX205Q is a very low cost dual-axis acceleration sensor on a monolithic IC. With no moving parts, the device is extremely reliable and is manufactured on a submicron CMOS process enabling small geometries and small die size, resulting in low overall cost and high functionality. The MX205Q is primarily designed for applications requiring high performance and where overall system cost is a driving factor in component selection. The MX205Q measures acceleration with a full-scale range of up to ± 5.0g and produces an Analog signal output. The X,Y accelerometer outputs are scaled proportionately to the VDD, VDA supply voltage with the scale of 44%. Typical noise floor is 750 µg/√Hz rms, allowing signals below 1 .0 milli-g to be resolved in 1 Hz bandwidth. Frequency response extends to 40 Hz. The frequency response can be extended to 160 Hz with the implementation of a simple external circuit. See Application Note (AN-00MX-003). The MX205Q is a dc accelerometer with the capability to measure both ac acceleration, (typical of vibration) or dc accelerations, (such as inertial force or constant, gravity-induced accelerations). The MX205Q offers a calibrated temperature sensor output with a positive temperature coefficient of 5.0 mV/°C. This device can be temperature compensated easily. The change in sensitivity over the temperature range –40°C to 125°...
