Single-Axis, High-g, iMEMS® Accelerometers

Vibration Control and Monitoring Vehicle collision sensing Shock Detection

Complete acceleration measurement system on a single monolithic IC Available ±35g, ±50g, or ±70g output full-scale ranges Full differential sensor and circuitry for high resistance to EMI/RFI Environmentally robust packaging Complete mechanical and electrical self-test on digital command Output ratiometric to supply Sensitive axis in the plane of the chip High linearity (0.2% of full-scale) Frequency response down to dc Low noise Low power consumption (1.3 mA) 400 Hz, 2-pole Bessel filter

The ADXL78 is a low power, complete single-axis accelerometer with signal conditioned voltage outputs that are on a single monolithic IC. This product measures acceleration with a full-scale range of ±35 g, ±50 g, or ±70 g (minimum). It can also measure both dynamic acceleration (vibration) and static acceleration (gravity).

The ADXL78 is the fourth-generation surface micromachined iMEMS® accelerometer from ADI with enhanced performance and lower cost. Designed for use in front and side impact airbag applications, this product also provides a complete cost-effective solution useful for a wide variety of other applications.

The ADXL78 is temperature stable and accurate over the automotive temperature range, with a self-test feature that fully exercises all the mechanical and electrical elements of the sensor with a digital signal applied to a single pin.

The ADXL78 is available in a 5 mm × 5 mm × 2 mm, 8-terminal ceramic LCC package.
