Breadboarding AIC3254

Other Parts Discussed in Thread: TLV320AIC3254

Hey
I am moving cautiously this time with the AIC3254 development.

Starting from scratch, building a breakout board for the IC to test it properly. First, please review these files regarding the correct design of the breakout board, specifically the solder mask tolerance
Gerber files and PDF images - https://drive.google.com/open?id=0B3tW8HqE_ubMNTZiTlNBamhBRTJTeTlQcE41MVFyNWllT2Uw

Eagle Schem File - https://drive.google.com/open?id=0B3tW8HqE_ubMWnEtcERCbkZ4UlJSc3Y2QW1pREs1dmVBQkhF

Eagle Board File - https://drive.google.com/open?id=0B3tW8HqE_ubMeWVCRm5NRzlhOFdFQzJFeUpYV2VFamVpR25V

Since SMD components cant be used, are there anything to note while breadboarding the components, like the tolerance of the through-hole resistor/capacitors, power source, etc

Also, attaching the codec schematic to be interfaced with an Arduino Uno.

Thanks.

PS - Maybe a little late to consult you but I should tell you that the board has already been fabricated and now waiting it to be assembled.

    Hi, Arjun,

    I will take a look at this and I will answer as soon as possible.

    Hi, Arjun,

    I have been checking your documents.

    Unfortunately, we don't have recommendations for breadboard components since the device is used with SMD components.

    If my understanding is correct, the AIC3254 adapter is already fabricated. So, you can't modify all these designs. The TLV320AIC3254 is suggested to be used with SMD components. Actually, it is recommended the use of capacitors near of the power supply and ref pins. So, SMD components would be the better option for this. Additionally, the differential inputs should be routed as parallel lines. So, the AIC3254 adapter could work but we cannot guarantee that it will be in optimal conditions.

    Best regards,
