The EVAL-ADXL356BZ is an analog output supporting a 10 g or 20 g accelerometer, the EVAL-ADXL356CZ is an analog output supporting a 10 g or 40 g, and the EVAL-ADXL357Z is a digital output supporting a 10.24 g, 20.48 g, or 40.96 g accelerometer. 15668-010 GENERAL DESCRIPTION Figure 1. EVAL-ADXL356BZ/EVAL-ADXL356CZ These evaluation boards are ideal for evaluating the ADXL356 and ADXL357 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. Note that the layout for the EVAL-ADXL354BZ/EVALADXL354CZ applies to both the EVAL-ADXL354BZ/EVALADXL354CZ and the EVAL-ADXL356BZ/EVAL-ADXL356CZ, and that the layout for the EVAL-ADXL355Z applies to both the EVAL-ADXL355Z and the EVAL-ADXL357Z. PLEASE SEE THE LAST PAGE FOR AN IMPORTANT WARNING AND LEGAL TERMS AND CONDITIONS. Rev. A | Page 1 of 5 15668-011 Full details about the ADXL356/ADXL357 are available in the ADXL356/ADXL357 data sheet, which is available from Analog Devices, Inc., and must be consulted in conjunction with this user guide when using this evaluation board.

The two 6-pin headers provide access to all other pins. Header P1 provides access to VDDIO (used to set the RANGE pin and the STBY levels on the ADXL356), VDD (which supplies the ADXL356 VSUPPLY pin), VSS/VSSIO (supply common connection), and XOUT, YOUT, and ZOUT, as shown in Figure 3.

EVAL-ADXL357Z Functional Block Diagram for Header P2 The vias or headers allow the evaluation boards to attach to either a prototyping breadboard or a printed circuit board (PCB) in an existing user system. Four holes are provided in the corners of the evaluation boards for mechanical attachment of the evaluation boards in many applications. An external host processor is required for communication to the ADXL357. The analog output of the ADXL356 must be connected to a band limited analog-to-digital converter (ADC). The dimensions of the evaluation boards are 0.8 in. x 0.8 in. CIRCUIT DESCRIPTION The evaluation board photograph of the EVAL-ADXL356BZ/ EVAL-ADXL356CZ is shown in Figure 1, and the evaluation board photograph of the EVAL-ADXL357Z is shown in Figure 2. The ADXL356/ADXL357 each have two power modes. They can be powered either by integrated, low dropout (LDO) regulators or by external user supplied 1.8 V regulated supplies. Refer to the ADXL356/ADXL357 data sheet for more information. HANDLING CONSIDERATIONS The EVAL-ADXL356BZ, the EVAL-ADXL356CZ, and the EVAL-ADXL357Z are not reverse polarity protected. Reversing any of the supply connections, including the VSS and the VSSIO pins, can cause damage to the ADXL356/ADXL357. Dropping the evaluation boards on a hard surface can generate several thousand g of acceleration, which can exceed the ADXL356/ADXL357 data sheet absolute maximum limits. VDDIO 1 3 5 P1 2 4 6 202-187 INT1 INT2 DRDY 15668-005 VDD Header P2 provides access to V1P8ANA, V1P8DIG, MISO/ASEL, CS/ SCL, SCLK/VSSIO, and MOSI/SDA, as shown in Figure 6. 15668-006 The EVAL-ADXL356BZ, the EVAL-ADXL356CZ, and the EVAL-ADXL357Z allow users to access the individual connections of the ADXL356 and the ADXL357. Each of the evaluation boards includes decoupling capacitors for the supplies, a few discrete resistors that provide isolation on the V1P8ANA and V1P8DIG pins, and two 6-pin headers. Refer to the ADXL356/ADXL357 data sheet for more details on the specific pin definitions. The power supplies for the ADXL356 and the ADXL357 are decoupled using multiple 0.1 F ceramic (0603) capacitors. Figure 5. EVAL-ADXL357Z Functional Block Diagram for Header P1 Rev.
