Description

The ADXL150/ADXL250 are third generation ±50 g surface micromachined accelerometers. These improved replacements for the ADXL50 offer lower noise, wider dynamic range, reduced power consumption and improved zero g bias drift.

TheADXL150/ADXL250  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 commercial 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.

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 ratiometric to the power supply, eliminating the need for a voltage 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 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 automotive and military temperature ranges.
