A DAC I2S 32BIT 384KHZ modular

This DAC I2S ESS ES9028Q2M module features a prominent design and components. It will offer the possibility to upgrade your DIY creations with compact and integrable cards for ambitious projects to be coupled with interfaces USB to I2S or ASO cards ALLO KALI including master clocks MCLK.

A modular analog section

A good DAC would be nothing without an analog part of high quality. the four AOPs are on DIP8 support type JRC5534 mono x2 and JRC5532 stereo X2. Thus, the sound signature corresponding to its HIFI system can be changed as desired. The options are therefore multiple with a wide choice of AOP interchangeable accessories.

A separate power supply Digital and analog

This DAC features a 15V +/- symmetrical power supply based on LM337T and LM317T controllers and a high quality low-voltage power supply LDO Linear Technology LT1963 on the digital part for better conversion accuracy of DAC ESS SABRE ES9028Q2M. The majority of the filter capacitors of this DAC are of ELNA for AUDIO origin.

This module requires a 9V AC transformer with a simple secondary winding as well as a transformer 15V AC with double secondary winding:

Transformer 5085 230V 15VX2 and 9VX1

Since this I2S DAC does not have any clock, it is imperative to connect to I2S a source with the necessary Masterclock (MCLK) signal.
