Description

A compact, high-quality DAC built around the well-regarded ESS ES9023, designed for clean, natural audio reproduction in DIY and embedded audio systems.

The analogue stage and power supply have been carefully considered, using a Texas Instruments TPS7A4901 low-noise regulator to ensure a stable and quiet supply to the DAC. High-quality thin film resistors and C0G/NP0 capacitors are used in the output stage, with proper decoupling throughout the board.

Ideal partnered with a Raspberry Pi/ESP board outputting I2S.

Compared to many low-cost DAC modules, this design focuses on component quality and layout.

• ESS ES9023 DAC chip
• Low-noise TPS7A4901 voltage regulation
• Thin film resistors in the audio path
• C0G/NP0 capacitors on the output stage
• Proper decoupling across the board
• No SCK needed
• 5-10V input

Designed for hobbyist and DIY audio applications where sound quality and simplicity are both important.
