ADXL350

Data Sheet

FEATURES

GENERAL DESCRIPTION

Excellent zero-g bias accuracy and stability with

minimum/maximum specifications

Ultralow power: as low as 45 μA in measurement mode and

0.1 μA in standby mode at V_S= 2.5 V (typical)

Power consumption scales automatically with bandwidth

User-selectable resolution

The high performance ADXL350 is a small, thin, low power,

3-axis accelerometer with high resolution (13-bit) and selectable

measurement ranges up to ±± g. The ADXL350 offers industry-

leading noise and temperature performance for application

robustness with minimal calibration. Digital output data is

formatted as 16-bit twos complement and is accessible through

either a SPI (3- or 4-wire) or I²C digital interface.

Fixed 10-bit resolution

Full resolution, where resolution increases with g range,

up to 13-bit resolution at 8 g (maintains 2 mg/LSB scale

factor in all g ranges)

Embedded, 32-level FIFO buffer minimizes host processor

load

Tap/double tap detection and free-fall detection

Activity/inactivity monitoring

Supply voltage range: 2.0 V to 3.6 V

The ADXL350 is well suited for high performance portable

applications. It measures the static acceleration of gravity in tilt-

sensing applications, as well as dynamic acceleration resulting

from motion or shock. Its high resolution (2 mg/LSB) enables

measurement of inclination changes of less than 1.0°.

Several special sensing functions are provided. Activity and

inactivity sensing detect the presence or lack of motion and if

the acceleration on any axis exceeds a user-set level. Tap sensing

detects single and double taps. Free-fall sensing detects if the

device is falling. These functions can be mapped to one of two

interrupt output pins.

I/O voltage range: 1.7 V to V_S

SPI (3- and 4-wire) and I²C digital interfaces

Flexible interrupt modes mappable to either interrupt pin

Measurement ranges selectable via serial command

Bandwidth selectable via serial command

Wide temperature range (−40°C to +85°C)

10,000 g shock survival

Low power modes enable intelligent motion-based power

management with threshold sensing and active acceleration

measurement at extremely low power dissipation.

Pb-free/RoHS compliant

Small and thin: 4 mm × 3 mm × 1.2 mm cavity LGA package

The ADXL350 is supplied in a small, thin, 3 mm × 4 mm ×

1.2 mm, 16-lead cavity laminate package.

APPLICATIONS

Portable consumer devices

High performance medical and industrial applications
