More info

This DAC kit with the new chipAKM AK4495EQandinput I2S allows to choose its interface USB or SPDIF not provided. One can thus design a DAC 16, 24 or 32bit up to 384Khz compatible DSD at low cost.

Several interfaces are possible:

By soldering a USB interface toI2S Amanero(not included), oneXMOS Audiophonics(not supplied), you can be assured that you haveDAC AK4495SEQUSB DSD high quality.

Interface Xmos USB / I2S Audiophonics.

Interface Amanero USB / I2S.

An SPDIF / I2S selector interface can also be used in the case of a coaxial SPDIF connection.

SPDIF I2S interface with display.

This DAC has a switch to switch the various digital filters (Sharp, Slow, apodizing, Slow Roll-Off.)

Quality control:

The power control part, a key element for a DAC AK 4495SEQis composed of two Texas Instruments LM2941Of typeMilitary LDO(Low Distortion Output) with an accuracy of 5% and a rejection greater than 65 dB at 100khz.

A controller LT1084 deals with higher tensions supported by two LM337T / LM317Tfrom Onsemi (Motorola).

At the price offered this DAC offers a stability of voltage of quality with recognized passive components: Vima MKP capacitorson the signal,Elna capacitorsfor power filtering. The diagram has 8 diodes upstream.

A simple transformer of 14 ~ 20 V is required for the power supply. 20 V toroidal transformer.

DIP 8 slot for output:

This DACof a DIP support 8with aJRC5532allowing the OP stereo dual amplifier of its choice to be changed. Many possibilities are possible (not provided):

OPA2134for a warm and shiny sound, OPA1612 for dynamic and straightforward sound, NJRMUSE 02for a tube type sound. LME49860 for precise and incisive sound.

Elecaudio RCAs are compatible with drillingof the PCB for a better finishing result: Elecaudio RCA ER106.
