GENERAL DESCRIPTION

The EVAL-ADMP521Z is a simple evaluation board that allows

quick evaluation of the performance of the

port, digital output, omnidirectional microphone. The EVAL-

ADMP521Z 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.

The EVAL-ADMP521Z is designed to plug directly into either row

of Connector J6 on the Analog Devices, Inc., 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.

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.

EVALUATION BOARD CIRCUIT

The schematic of the EVAL-ADMP521Z is shown in Figure 1.

See the

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.
