描述：The EVAL-ADMP521Z is an evaluation board for the device ADMP521Z. The EVAL-ADMP521Z is a simple evaluation board that allows quick evaluation of the performance of the ADMP521 bottom port, Digital output, omnidirectional microphone. The EVALADMP521Z has a dual-row, 12pin, 0.1-inch spaced header for access to all microphone pins. All signals are connected to the row of pins along the edge of the board. The pins on the inner row are not connected to any signals. The EVAL-ADMP521Z is designed to plug directly into either row of connector J6 on the EVAL-ADAU1761Z evaluation board. When these two boards are connected, the EVAL-ADMP521Z board should extend off the left edge of the EVAL-ADAU1761Z board. . Small and thin 3mm × 4mm × 1mm Surface mount package .
