I’ve designed a system to generate Analog Audio Line Out from an I2S Digital Input using TLV320AIC3106. The schematics page is attached alongside. Please help me to confirm the following. Use of MCLK, its frequency used. Line Output pins , the reference signal used. GND connections to IC. Thanks in advance. If you need line – in on the ESP32-P4, you can use any of the other boards above on the P4, using different I2S pins from the on-board I2S codec chip. Support for the ES8311 chipset is derived from the Espressif ESP32-P4 EV dev board: This has also been confirmed on the Waveshare ESP32-P4 Nano boards as well, which use the same pins: Pin Config. I have a circuit that feeds a I2S bus into a PCM5101A chip, which outputs a analog signal that is used by the circuit. I have tried tapping into the analog signal coming out from the PCM5101A chip, but the sound gets distorted when there is a lot of lower frequencies in the music that is being played. Now I am searching for an I2S – Decoder with line – in – compatible output . I don’t want to use a small 3W 4 Ohm speaker I want to feed in the audio-signal in any kind of Audio-amplifier. No PWM, real audio at 0,7V to 1V voltage-level = line-in compatible . I found a product at adafruit. Connection to DAC can be made either through the 16 – pin header or using MMCX for I2S with separate wiring for I2C , GPIOs and isolator power. In my DACs I have “sandwiched” the USB-I2S board with DAC board as all my DAC boards have same format and connector placement. We’re starting to stock a lot of chips that are able to do digital I2S out , which makes for great-quality audio playback. That’s great when you have enough processing power to decode WAVs or MP3s in real-time. However, we could really use some better DACs in the shop.
