No additional external components are required for operation. The EVAL-ADXRS624 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.

As delivered, the EVAL-ADXRS624 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. 3A 7C 7E 6G 2G C5 C1 1D VDD 13 PGND 12 NC = NO CONNECT Figure 1.

PLEASE SEE THE LAST PAGE FOR AN IMPORTANT WARNING AND LEGAL TERMS AND CONDITIONS. SUMJ C3 CP1 19 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 EVAL-ADXRS624 is not reverse polarity protected. Reversing the power supply or applying inappropriate voltages to any pin (outside the Absolute Maximum Ratings listed in the ADXRS624 data sheet) may damage the EVAL-ADXRS624. 3 C4 The schematic of the EVAL-ADXRS624 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 ADXRS624 data sheet.
