GENERAL DESCRIPTION

The ADXL202EB is a simple evaluation board that allows the user to quickly evaluate the performance of the ADXL202 dual axis ± 2 g accelerometer. Only three additional through-hole passive components must be added, depending on the bandwidth required in your application. The ADXL202EB has a 5-pin 0.1-inch spaced header for access to all power and signal lines that may be attached to a prototyping board (breadboard) or wired via a standard plug. Two holes are provided for mechanical attachment of the ADXL202EB to your application.

CIRCUIT DESCRIPTION

The schematic and parts list of the ADXL202EB are shown in Figure 1 and Table I respectively. The minimal application will require at least one resistor (RSET) added to the board to set the PWM period (T2). Analog bandwidth may be set by adding capacitors C2 and C3. Refer to the ADXL202 data sheet for a complete description of the operation of the accelerometer.
