Description

The AD22280 is a complete single-axis accelerometer with signal conditioned voltage outputs that are available in ±35 g, ±50 g, or ±70 g output full-scale ranges. It can measure acceleration with both dynamic acceleration (vibration) and static acceleration (gravity) and is highly resistant to EMI/RFI thanks to its full differential sensor and circuitry. In addition, it has a tight sensitivity tolerance and 0 goffset capability, a largest available prefilter clipping headroom and 400 Hz, 2-pole Bessel filter. It has a high level of linearity (0.2% of full scale), a frequency response down to dc, low noise, a low power consumption (1.3 mA) and is environmentally robust. It is also compatible with Sn/Pb and Pb-free solder processes and qualified for automotive applications.
