High Performance, Wide Bandwidth Accelerometer Evaluation Board EVAL-ADXL001 VDD GENERAL DESCRIPTION C1 0.1µF VDD2 8 DNC 1 7 ADXL001 VDD XOUT DNC 2 6 COM 3 5 DNC R1 C2 4 ST 07619-001 The EVAL-ADXL001 is a simple evaluation board that allows users to quickly evaluate the performance of the ADXL001 vibration sensor. The EVAL-ADXL001 is specifically designed to mount on to a mechanical shaker and is constructed of an extra thick PCB, measuring 0.8 inches square. Screw holes are supplied for rigid mounting to the shaker block. This design allows users to easily evaluate the full performance range of the ADXL001 vibration sensor without having to solder the device to a separate test board. Solder pads are included that allow users to implement their own application-specific low-pass filter on the output of the device. NOTES 1. DNC = DO NOT CONNECT. 2. R1 AND C2 ARE SUPPLIED BY THE USER. Figure 1. EVAL-ADXL001 Schematic CIRCUIT DESCRIPTION 0.8" The schematic for the EVAL-ADXL001 is shown in Figure 1. This circuit was designed to allow for a user-configurable lowpass filter on the device output. When no low-pass filter is needed, users must short the R1 solder pads together, and it is recommended that a bypass capacitor (22 nF) be placed on C2 for improved EMI rejection. C1 VDD GND 0.8" SPECIAL NOTES ON HANDLING ADXL001 XOUT 0.58" DNC R1 ST 07619-002 VDD and VDD2 are shorted together internally on the PCB. This is consistent with normal device operation. The board layout of the EVAL-ADXL001 is shown in Figure 2 and the parts list for the EVAL-ADXL001 is shown in Table 1. As delivered, there is no bandwidth limit set for the ADXL001. It is recommended that a ~75 kHz low-pass filter be added to mitigate high frequency noise outside of the vibration band of interest. C2 Figure 2. EVAL-ADXL001 Board Layout Table 1. EVAL-ADXL001 Parts List Component C1 C2 R1 Value (nF) 100 Not included Not included The EVAL-ADXL001 is not reverse polarity protected. Reversing the power supply or applying inappropriate voltages to any pin may damage the EVAL-ADXL001. Rev. 0 Evaluation boards are only intended for device evaluation and not for production purposes.
