Philips TDA1543A

Hi,

Can any one tell me what a Philips TDA1543A is, I have the TDA1543 data sheet and there is no mention of an A variant, I have been offered both the TDA1543 and the TDA1543A by the same vendor.

Hi Mozfet,
Yes this is a extremely confusing act of the Philips Gloeilampen Fabriek located in Eidhoven the Netherlands. They don't bother to write a correct datasheet.
I have two TDA1543A that only produce noise when connected to the CS8412 digital inputreceiver whether in I2S mode or the Sony/BB mode; LSBJ in the Cirrus jargon. This version seems not to be suited for the two's complement format used by Sony/BB & Philips I2S but for the offset binary format.
Don't ask me to explain the exact difference beteen two's complement & offset binary.
The TDA1543 seems to be suitable for the I2S format as obtained from the CS8412 (two's complement)
You are luckey as you have the choice with your vendor. I ordered two TDA1543 and got two TDA1543A that are useless to me!Thank you Philips!

Thanks! I thought I was going nuts! I'm assuming here that the only difference, (performance wise) between the 8 pin TDA1543 and the TDA1543T is the package, or am I missing something here?

Hi Mozfet,
Ooooh the T
That's the 14 pin SMT version.(SOT162-1). These have no A so should be two's complement
