Question Odd tda1541 voltages / implementation


Just looked at the saa7220 datasheet.

Two things I thought a bit odd:-

1. tda1541 pin 4 has a separate clock!

2.tda1541 has a -12v supply on Vdd2

Is this -12v right or an error ?

I like the idea of the pin4 clock, different from my Arcam where pin 2, and 4 are connected!

Kind regards,

This is only possible on the original TDA1541...and not possible on TDA1541A. It refers to this in the TDA1541 data sheet....but there is no mention of it in the TDA1541A data sheet.
