Single-Axis, High-g,

MEMS^®Accelerometers

ADXL78

FEATURES

GENERAL DESCRIPTION

Complete acceleration measurement system on a

single monolithic IC

Available in 35 g, 50 g, or 70 g 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

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 ±±3 g, ±35 g, or ±75 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-

Output ratiometric to supply

Sensitive axes in the plane of the chip

High linearity (0.2% of full scale)

Frequency response down to dc

effective solution useful for a wide variety of other applications.

Low noise

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.

Low power consumption (1.3 mA)

Tight sensitivity tolerance and 0 g offset capability

Largest available prefilter clipping headroom

400 Hz, 2-pole Bessel filter

Single-supply operation

Compatible with Sn/Pb and Pb-free solder processes

The ADXL78 is available in a 3 mm × 3 mm × 2 mm,

8-terminal ceramic LCC package.

APPLICATIONS

Vibration monitoring and control

Vehicle collision sensing

Shock detection
