GENERAL DESCRIPTION

The typical noise floor is 200 ␮g√Hz, allowing signals below

2 mg (at 60 Hz bandwidth) to be resolved.

The ADXL210E is a low-cost, low-power, complete 2-axis acceler-

ometer with a digital output, all on a single monolithic IC. It is an

improved version of the ADXL210AQC/JQC. The ADXL210E

will measure accelerations with a full-scale range of 10 g. The

ADXL210E can measure both dynamic acceleration (e.g., vibra-

tion) and static acceleration (e.g., gravity).

The bandwidth of the accelerometer is set with capacitors C_Xand

C_Yat the X_FILTand Y_FILTpins. An analog output can be recon-

structed by filtering the duty cycle output.

The ADXL210E is available in a 5 mm ϫ 5 mm ϫ 2 mm 8-lead

hermetic LCC package.

The outputs are analog voltage or digital signals whose duty cycles

(ratio of pulsewidth to period) are proportional to acceleration.

The duty cycle outputs can be directly measured by a micro-

processor counter without an A/D converter or glue logic. The

duty cycle period is adjustable from 0.5 ms to 10 ms via a single

resistor (R_SET).
