2 Signal Chain Architecture

For systems with up to 8 analog input channels, 8 digital input channels, or 16 digital microphone inputs routed through the DAC signal chain, four TAx5xxx-Q1 devices can synchronize gain adjustments with the ICLA algorithm. TAx5xxx-Q1 supports a shared I²C control bus and audio serial bus using a time-division multiplexed (TDM), Inter-IC Sound (I²S), or Left-justified (LJ) interface. Figure 2-1 shows a diagram of four TA(C/D)5XXX devices connected for ICLA with digital inputs on a shared audio serial bus.

Figure 2-2 shows a diagram of four TAC5xxx-Q1 devices connected for ICLA with 8 analog channels.

Internal ADC channel output loopback is not supported when configuring more than 2 devices for ICLA synchronization due to slot reservation for ICLA communication. Figure 2-3 shows a diagram for routing multiple devices to record and playback with a manual loopback circuit design.
