Introduction:

TDA1541A chip Audiophile DAC circuit based on PHILIPS generation of classic DA chip, optimized design to achieve lower distortion and high SNR. Medium frequency transparent have lasting appeal, embellish thick excellent voice.

 

Some people say that this is "musicality", but it is more clear and easy to understand. In fact, TDA1541A allows you to listen to music for a longer time without feeling tired. Perhaps this is why the TDA1541A, which has been out of production for a long time, still has a place in the sound industry.

 

PCB design follows some circuits of HIFI Forum 10th Anniversary TDA1541, and is adjusted and upgraded; The PCB is designed with military grade 1.6mm thickness and 4-layer gold plating special process. In the sense of hearing, the medium frequency density and thickness are significantly improved. Besides, the high and low frequencies are extended, and the sound is more cohesive and durable.

Parameters:
Coaxial input: 0.5 Vp-p/75ohms;
Sampling frequency: 44.1/48kHz;
SN: >106dB or more;
Dynamic range:>97dB or more;
Resolution:>100dB or more
THD: < 0. 0015% (1kHz)
Size: 200mm*174mm

 

【EXT IN】Extension input interface:

V: Positive power supply 5V

G: Negative pole of power supply

D: Coaxial input

G: Negative pole of power supply

 

Use this interface to connect USB module, Bluetooth module, optical fiber module;

 

When using the EXT IN interface input, please unplug the RCA plug, this interface occupies the RCA coaxial input, At the same time, a C2 * capacitor must be installed, and the capacitance can be 0.1~1uF.

 

NOTE: This is the Bare PCB. You need to match all the parts yourself.
