A B ( P1 and P13)
P13 is used to connect towards the next sub board and P1is used to connect towards the main board. These con-
nectors allow the AD2437 on the EVAL board to talk to other A

XLR cable assembly

Audio I2S Connector ( P2)

Multipurpose connector containing all a combination of SIO, clock, and GPIO signals.

Class D Speaker Connectors ( P16-P18 )

P16-P18 are the outputs of the Class - D amplifier and are used to connect stereo speakers to the board. Please
ensure that the chosen speaker is no less than 8 ohms.

ADC Input Connector ( P4 )

The ADAU1701 has two Σ-Δ ADCs. P4 will supply both signals through a 3.5mm Stereo TRS connector. The
signal-to-noise ratio (SNR) of the ADCs is 100 dB, and the THD + N is −83 dB.

3.5mm Stereo TRS connector

DAC Output Connector ( P6 and P7 )

The ADAU1701 includes four Σ-Δ DACs. The SNR of the DAC is 104 dB, and the THD + N is −90 dB. A full-
scale output on the DACs is 0.9 V rms (2.5 V p-p). The DACs are in an inverting configuration. If a signal inver-
sion from input to output is undesirable, it can be reversed either by using an inverting configuration for the output
filter or by simply inverting the signal in the SigmaDSP program flow.
