The ADXL150 and ADXL250 are third generation ±50 g sur-  
face micromachined accelerometers. These improved replace-  
ments for the ADXL50 offer lower noise, wider dynamic range,  
reduced power consumption and improved zero g bias drift.

The ADXL150 is a single axis product; the ADXL250 is a fully  
integrated dual axis accelerometer with signal conditioning on a  
single monolithic IC, the first of its kind available on the com-  
mercial market. The two sensitive axes of the ADXL250 are  
orthogonal (90°) to each other. Both devices have their sensitive  
axes in the same plane as the silicon chip.

ratiometric to the power supply, eliminating the need for a volt-  
age reference when driving ratiometric A/D converters such as  
those found in most microprocessors. A power supply bypass  
capacitor is the only external component needed for normal  
operation.  
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 10× improvement  
over the ADXL50. Power consumption is a modest 1.8 mA  
per axis. The scale factor and zero g output level are both  
The ADXL150/ADXL250 are available in a hermetic 14-lead  
surface mount cerpac package specified over the 0°C to +70°C  
commercial and –40°C to +85°C industrial temperature ranges.  
Contact factory for availability of devices specified over automo-  
tive and military temperature ranges.
