The EVALADXL372Z is ideal for evaluation of the ADXL372 in an existing system because the stiffness and the small size of the evaluation board minimize the effect of the board on both the system and acceleration measurements. EQUIPMENT NEEDED External host processor DOCUMENTS NEEDED Full specifications for the ADXL372 are available in the product data sheet; consult the data sheet in conjunction with this user guide when working with the evaluation board.

The vias or headers allow attachment of the evaluation board either to a prototyping board (breadboard) or to a printed circuit board (PCB) in an existing system. Four holes are provided that are set 15 mm × 15 mm at the corners of the PCB for mechanical attachment of the EVAL-ADXL372Z to the application fixture. An external host processor is required for communication to the device. The dimensions of the EVAL-ADXL372Z are 20 mm × 20 mm. CIRCUIT DESCRIPTION The PCB layout of the EVAL-ADXL372Z is shown in Figure 1. The EVAL-ADXL372Z is equipped with three factory installed capacitors for bypass: two 0.1 μF capacitors (C1 and C2) and a 10 μF capacitor (C3). C2 and C3 are VS bypass capacitors for reducing analog supply noise and C1 (located between VDDI/O and GND) is for reducing digital clocking noise. The schematic of the EVAL-ADXL372Z is shown in Figure 2. See the ADXL372 data sheet for information on configuring the accelerometer following its connection to the application host processor. HANDLING CONSIDERATIONS The EVAL-ADXL372Z is not reverse polarity protected. Reversing the VS or VDDI/O supply and GND pins can cause damage to the ADXL372. Dropping the EVAL-ADXL372Z on a hard surface can generate several thousand g of acceleration, which may exceed the data sheet absolute maximum limits. See the ADXL372 data sheet for more information.
