choosing TDA1543

sparkle · 6th February 2006, 09:55 AM

Hello guys,
one question.... If i run TDA1543 on a 8,6V and have I2V resistors 2k4 and referent resistor 1k5 (not that i am running TDA1543 on that voltage - to hot for me but... ) how to choose which TDA1543 would be the best for the job.... if i have 20 chips and have to select the best out of them that would be able to work on that situation up there also ..... any tips?
best regards

i would like to know how it would be possible to pick the best chip out of the box with 20 chips of TDA1543 ? ......
what are the parameters?
How to do that?
regards

TDA1543 is the simplest to use, im looking for one myself.

The TDA1543 you can connect directly to the spdif receiver like CS8412 or anything with the same kind of data outputs.

that is not a problem.... i have the dac that is working for over a year.... the question is how to select the best chip out of the 20 same looking chips.... how to select the best one.....

Use a -60db 1khz sine and select for low distortion .. should be a start.

hmmm.... is there any way that i can use without having function generator and osciloscope? something......

burn a wav file on CD, download analyzer software and use soundcard as hardware.

Hi,

Tried that today.

My sound card isn't very good!

Useful nonetheless..

Kind regards,
