I will design digital audio dac adc codec i2s tdm pcb

I design digital audio PCBs built around DAC, ADC, audio codec, I2S, and TDM interfaces, for professional and embedded audio applications where the digital and analog sides both need to be handled correctly.

The tricky part of these boards is the interface between digital and analog I2S and TDM buses carrying multi-channel audio data need clean clocking and careful trace routing, while the DAC/ADC output stage needs to be isolated from digital noise so it doesn't leak into your signal.

I lay these boards out with that separation built in from the start, not fixed after the fact.

This covers standalone DAC/ADC boards, embedded audio interfaces for larger products, and multi-channel systems using I2S or TDM for connecting multiple codecs or processors. If you already have a schematic, I move to layout.

If you're starting from chip selection, I can help build the schematic first.

You'll get the schematic (if needed), PCB layout, Gerbers, and BOM.

Inbox me your chip selection or project concept, along with channel count and interface requirements, and I'll confirm scope and pricing.
