The EVALADXL354BZ is an analog output supporting a ±2 g or ±4 g accelerometer; the EVAL-ADXL354CZ is an analog output supporting a ±2 g or ±8 g accelerometer; and the EVAL-ADXL355Z is a digital output supporting ±2 g, ±4 g, or ±8 g. These evaluation boards are ideal for evaluating the ADXL354 and ADXL355 in an existing system because the stiffness and small size of the evaluation board minimizes the effect of the evaluation board on both the system and acceleration measurements. 14832-001 GENERAL DESCRIPTION Figure 1. EVAL-ADXL354BZ and EVAL-ADXL354CZ Evaluation Boards 14832-002 Full details about the ADXL354/ADXL355 are available in the ADXL354/ADXL355 data sheet, which is available from Analog Devices, Inc., and should be consulted in conjunction with this user guide when using this evaluation board.

Each of the evaluation boards include decoupling capacitors for supplies, a few discrete resistors to provide isolation on the V1P8ANA and V1P8DIG pins, and two 6-pin headers. Refer to the ADXL354/ ADXL355 data sheet for more detail on specific pin definitions. The power supplies for the ADXL354/ADXL355 is decoupled using multiple 0.1 μF ceramic (0603) capacitors.

EVAL-ADXL355Z Function Block Diagram for Header P2 The vias or headers allow the evaluation boards to attach to either a prototyping breadboard or to a printed circuit board (PCB) in an existing user system. Four holes are provided in the corners of the evaluation board for mechanical attachment of the evaluation boards in many applications. An external host processor is required for communication to the ADXL355, while the analog output of the ADXL354 must be connected to a band limited analog-to-digital converter (ADC). 202-187 CIRCUIT DESCRIPTION 14832-003 1 Figure 3.

The ADXL354 and ADXL355 each have two moded by which they can be powered: by integrated low dropout regulators (LDOs) or external, user supplied 1.8 V regulated supplies. Refer to the ADXL354/ADXL355 data sheet for more information. HANDLING CONSIDERATIONS 14832-004 V1P8ANA 202-187 INT1 4 The dimensions of the evaluation boards are 0.8 in × 0.8 in. VDD VDDIO 5 2 3 14832-006 The EVAL-ADXL354BZ and EVAL-ADXL354CZ evaluation boards have capacitors on each axis output to set the output low-pass filter and two 3-position jumpers to configure Range and Mode. The two 6-pin headers provide access to all other pins. Header P1 provides access to VDDIO (sets the RANGE pin and the STBY pin levels on the EVAL-ADXL354BZ and EVALADXL354CZ evaluation boards), VDD (supplies the ADXL354 VSUPPLY pin), VSS/VSSIO (supplies the ground connection), XOUT, YOUT, and ZOUT, shown in Figure 3. Header P2 provides access to V1P8ANA, V1P8DIG, TEMP, ST1, ST2, and VSS (supplies the ground connection), shown in Figure 4. P1 1 Figure 4. EVAL-ADXL354BZ and EVAL-ADXL354CZ Function Block Diagram for Header P2 The EVAL-ADXL355Z uses two 6-pin headers to provide access to all pins. Header P1 provides access to VDDIO, VDD (which is connected to the ADXL355 VSUPPLY pin), VSS/VSSIO (supply ground connection), INT1, INT2, and DRDY, shown in Figure 5. Header P2 provides access to V1P8ANA, V1P8DIG, MISO/ASEL, CS/SCL, SCLK/VSSIO, and MOSI/SDA (see Figure 6). The EVAL-ADXL354BZ, EVAL-ADXL354CZ, and EVALADXL355Z evaluation boards are not reverse polarity protected. Reversing any of the supply connections, including the VSS and VSSIO pins, can cause damage to the ADXL354/ADXL355. Dropping the evaluation boards on a hard surface can generate several thousand g of acceleration, which can exceed the ADXL354/ADXL355 data sheet absolute maximum limits. Rev.
