TDA1315 and TDA1543?

[figge77]

i have these parts lying in the workshop and i got the bright idéa to make a dac of them. any clue as to where i can find a simple schematic?

i sat and looked at the datasheet for the 1315 but i didnt come up with any idéas of a simple schematic.

also found some other cheapo dacs for ex LC7881, PCM67, PCM55(SMD) so it sucks.
from what i can tell the TDA1543 and possibly LC7881 are the simplest to actualy build something with.

any idéas what i could do with the stuff?

have some 1541´s and 1545´s but they are reserved for other projects.

You could look at making a DDDAC DAC with the TDA1543s, especially if you have a lot of them.

I don't think there is a very useful way to use a TDA1315 in a simple circuit. It needs a microcontroller to make it do anything interesting.

thank you for the info.

the project is scraped before it started...not very unusual.

so no more buchering DCC players for the receiver chip.

TDA1315 works just fine as a receiver in a stand-alone application (no CPU). Just read the datasheet.
FYI generally the jitter performance of the TDA1315 is extremely dependant on the quality of iot's analogue supply (which powers the built in clock recovery PLL), and the PLL loop filter. A good place to look is the Marantz CD-7 service manual...
