Description:
After a period of test and experience, the 1540DAC was redesigned with the third version of the circuit as the core.
Compared to the third edition:
1. The power supply module has been added, so that the power supply of each module is independently regulated
2. Delay protection circuit is added, the switch will be delayed for a
period of time and then the output will be started, which can better
protect the latter stage
3. Optimized the power supply and ground wire layout, which greatly improves the sound quality
4. Redefine the input and output interface, which is more suitable for installing a chassis
5. Compatible with the modules of the third version
6. Added I2S input function, the board can directly three-wire I2S signal, (LRCK, BCK, DATA, GND)
Specification:
- TDA1540 DAC fifth edition DAC0_5
- Finished board (CS8412+SAA7030+TDA1540P)
- Size: 280x200
The
audition results of this board (plastic package TDA1540+plastic package
5532), can be close to the 8K machine of a major foreign manufacturer.
Replacement of the ceramic seal TDA1540D, and the op amp, will bring
greater improvement
