This small 70x45 mm device is capable of handling every requirement to process your analog as well as digital audio. You can build stereo, 2 channel, 2.1 channel, 4 channel or even 4.1+ audio systems by using this device. Device runs in both Master & Slave mode.
Device has 4 GPIOs which can be configured to connect potentiometers, LEDs or other components. It has flexibility, where you can connect Bluetooth devices with both Digital or Analog outputs.
Build stereo, 2-channel, 2.1-channel or 4-channel audio systems with ADAU1701 + TDA7388 QUAD Amplifier on the fly. You can power TDA7388 with up to 18V DC and power ADAU1701 DSP with the 5V DC Out from TDA7388. Connect 3.5 mm Audio cables from DSP to amplifier, connect 4 speakers and your 4-channel audio system is ready.
You can additionally connect 100W TAS5828m Mono Amplifier with the existing setup by simply connecting Digital Out from ADAU1701 DSP to Digital Input to TAS5828m. You must power TAS5828M separately.
