Evaluating the ADXL354/ADXL355 Low Noise, Low Drift, Low Power,
3-Axis MEMS Accelerometers
FEATURES
PRINTED CIRCUIT BOARD LAYOUT
2 sets of spaced vias for populating 6-pin headers
Easily attachable to prototyping board or PCB
Small size and board stiffness minimize impact on the
system being monitored and acceleration measurements
EQUIPMENT NEEDED
External host processor

ADXL354/ADXL355 data sheet
The EVAL-ADXL354BZ, EVAL-ADXL354CZ, and EVALADXL355Z are simple evaluation boards that allow quick
evaluation of the performance of the ADXL354 and the ADXL355
low noise, low power, 3-axis, MEMS accelerometer. 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.

EVALUATION BOARD HARDWARE
VDD VDDIO
The EVAL-ADXL354BZ, EVAL-ADXL354CZ, and EVALADXL355Z evaluation boards allow users to access the individual
connections of the ADXL354 and ADXL355. 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.

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).

The PCB layout of the EVAL-ADXL354BZ, EVAL-ADXL354CZ,
and EVAL-ADXL355Z evaluation boards are shown in Figure 2.
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.

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.

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.
