Product Details

The ADXL204 is a high precision, low power, complete dual-axis accelerometer with signal-conditioned voltage outputs, all on a single monolithic IC. Like the ADXL203, it measures acceleration with a full-scale range of ±1.7 g; however, the ADXL204 is tested and specified for 3.3 V supply voltage, whereas the ADXL203 is tested and specified at 5 V. Both parts function well over a wide 3 V to 6 V operating voltage range. The ADXL204 can measure both dynamic acceleration (for example, vibration) and static acceleration (for example, gravity).

The typical noise floor is 170 µg/√Hz, allowing signals below 2 mg (0.1° of inclination) to be resolved in tilt sensing applications using narrow bandwidths (<60 Hz).

The user selects the bandwidth of the accelerometer using Capacitor CX and Capacitor CY at the XOUT and YOUT pins. Bandwidths of 0.5 Hz to 2.5 kHz can be selected to suit the application.

The ADXL204 is available in a 5 mm × 5 mm × 2 mm, 8-terminal hermetic LCC package.
