When these two boards are connected, the EVAL-ADMP521Z board should extend off the left edge of the EVAL-ADAU1761Z board. Circuit Note CN0078 fully describes the connection between these two boards and the register settings of the codec. The dimensions of the EVAL-ADMP521Z are 13 mm × 18 mm. The evaluation board is RoHS-compliant part. U1 ADMP521 3 CLK 1 2 4 VDD L/R SELECT DATA 5 4 5 C1 0.1µF GND 6 3 7 L/R SELECT 8 9 DATA 10 11 VDD 12 Figure 1.

See the ADMP521 data sheet for a complete description and microphone specifications. The PCB layout of the EVAL-ADMP521Z is shown in Figure 2. The factory-installed 0.1 μF capacitor, C1, is a bypass capacitor that reduces supply noise and ensures proper microphone operation. The board is powered from a single 1.8 V to 3.3 V supply on Pin 11 of the connector. The EVAL-ADMP521Z connector pin functions are described in Table 1. CLK 10284-001 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, 12-pin, 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. GND 2 C1 11 12 10284-002 GENERAL DESCRIPTION Figure 2. PCB Layout Table 1.
