ADXL150 Datasheet – Single Axis Accelerometer – IC

The ADXL150 is a Low Noise, Low Power, Single Axis iMEMS Accelerometer made by Analog Devices, supplied in an SOP 14 Pin Type package. The absolute maximum ratings table on this page lists the 5 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the ADXL150 pinout and maximum ratings, with the full datasheet PDF to preview below or download.

The ADXL150 and ADXL250 are third generation ± 50 g sur- face micromachined accelerometers. These improved replacements 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.

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 radiometric to the power supply, eliminating the need for a voltage reference when driving radiometric 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 calpac 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.
