The ADXL150/ADXL250 offer lower noise and improved signal-to-noise ratio over the ADXL50. Typical S/N is 80 dB, allowing resolution of signals as low as 10 mg, yet still providing a 50 g full-scale range. Device scale factor can be increased from 38 mV/g to 76 mV/g by connecting a jumper between VOUT and the offset null pin. Zero g drift has been reduced to 0.4 g over the industrial temperature range, a 10x improvement over the ADXL50. Power consumption is a modest 1.8 mA per axis. The scale factor and zero g output level are both
