Evaluating the ±250°/Sec, Single Chip Rate Gyro
PLEASE SEE THE LAST PAGE FOR AN IMPORTANT
WARNING AND LEGAL TERMS AND CONDITIONS.Rev. 0 | Page 1 of 2
GENERAL DESCRIPTION
The E VA L -ADXRS622 is a simple evaluation board that
allows quick evaluation of the performance of the ADXRS622
±250°/sec yaw rate gyro. No additional external components are
required for operation. The EVAL-ADXRS622 has a 20-lead,
dual in-line (0.3 inch width × 0.1 inch pin spacing) interface
that allows easy prototyping of products without BGA
soldering.
CIRCUIT DESCRIPTION
The schematic of the EVA L-ADXRS622 is shown in Figure 1.
The numbers that appear in squares correspond to the pins on
the evaluation board. It is identical to the suggested application
shown in the ADXRS622 data sheet.
The analog and power grounds (AGND and PGND) have
separate power planes in this evaluation board to accommodate
application-specific grounding schemes. If the user requires
only a single ground plane, these nodes can be shorted together.
Both AGND and PGND must be grounded for the evaluation
board to operate properly.
Note that the analog supply voltage and charge pump supply
voltage (AVCC and VDD) are not connected on the E VA L -
ADXRS622 and that the user can connect these as appropriate
to their application.
The parts layout of the EVA L-ADXRS622 is shown in Figure 2,
and the parts list for the E VA L -ADXRS622 is shown in Table 1.
As delivered, the E VA L -ADXRS622 is set to 10 Hz bandwidth
(COUT = 100 nF). The user can add an external capacitor to
further reduce the bandwidth and improve the noise floor.
SPECIAL NOTES ON HANDLING
Note that the EVAL-ADXRS622 is not reverse polarity
protected. Reversing the power supply or applying
inappropriate voltages to any pin (outside the Absolute
Maximum Ratings listed in the ADXRS622 data sheet) may
damage the EVAL-ADXRS622.
