| Small, Low Power, 3-Axis 2 g i MEMS(R) Accelerometer Preliminary Technical Data FEATURES 3-axis sensing Small, low-profile package 4 mm x 4 mm x 1.45 mm LFCSP Low power 200 A at VS = 2.0 V (typ) Single-supply operation 2.0 V to 3.6 V 10,000 g shock survival Good zero g bias stability Good sensitivity accuracy BW adjustment with a single capacitor RoHS/WEEE lead-free compliant ADXL330 GENERAL DESCRIPTION The ADXL330 is a small, low power complete three axis accelerometer with signal conditioned voltage outputs, all on a single monolithic IC. The product measures acceleration with a minimum full-scale range of 2 g. It can measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion, shock, or vibration. The user selects the bandwidth of the accelerometer using capacitors CX, CY, CZ and at the XOUT, YOUT, and ZOUT pins. Bandwidths may be selected to suit the application, with a range of 0.5 Hz to 1,600 Hz for X and Y axes, and a range of 0.5 Hz to 550 Hz for the Z axis. The ADXL330 is available in a small, low-profile, 4 mm x 4 mm x 1.45 mm, 16-lead, plastic lead frame chip scale package (LFCSP).

Sensitivity is essentially ratiometric to VS. For VS = 2.7 V to 3.3 V, sensitivity is TBD mV/V/g to TBD mV/V/g typical. 3 Defined as the output change from ambient-to-maximum temperature or ambient-to-minimum temperature. 4 Actual frequency response controlled by user-supplied external filter capacitors (CX, CY, CZ). 5 Bandwidth with external capacitors = 1/(2 x x 32 k x C). For CX, CY, CZ = 0.003 F, bandwidth = 1.6 kHz. For CX, CY, CZ = 10 F, bandwidth = 0.5 Hz. 6 Self-test response changes cubically with VS. 7 Turn-on time is dependent on CX, CY, CZ and is approximately 160 x CX or CY or CZ + 1 ms, where CX, CY, CZ are in F.

Parameter Acceleration (Any Axis, Unpowered) Acceleration (Any Axis, Powered) VS All Other Pins Output Short-Circuit Duration (Any Pin to Common) Temperature Range (Powered) Temperature Range (Storage) Rating 10,000 g 10,000 g -0.3 V to +7.0 V (COM - 0.3 V) to (VS + 0.3 V) Indefinite -55C to +125C -65C to +150C Preliminary Technical Data Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Rev.
