TDA1540 drive board Support 256FS 384Fs I2S input drive HIFI Audio DAC DIY
WM8805 uses SCM soft control, digital accept module can support 44.1K 48K 88.2K 96K 176.4K 192K, but in OS mode, digital filtering SAA7030 only supports 44.1 and 48K; NOS mode (remove SAA7030), can support 192K playback. The soft control 8805 can make the 8805 work in the best condition; the actual test found that the soft control 8805 is better than the 8412 in terms of detail and resolving power.
Digital Processing Chip Using SAA7030
Using ceramic cap TDA1540D
The output part uses a specially designed open-loop current buffer module, and all the resistors on the board use a high-precision crystal resistor.
Chip capacitors using X7R COG
DALE resistors are used for all resistors, and HIFI topping capacitors such as ROE Philips are used for capacitors.
The default output level of the board is RMS 2.5V, Vpp 3.4V, the initial power, please pay attention to control the front level volume.
