Other Parts Discussed in Thread: TAS5414
Gregg,
I've married the TPA6304 EVM board to my recently-minted "break-out board".
I might have made a design mistake assuming that TPA6304's IN_M voltage rail is ~3.3VDC as the earlier TAS5414 was.
But I'm measuring IN_M at 2.6VDC under the load of a 10M ohm scope probe.
Is this correct?
The IN_M voltage is significant to me because I bring it into my board, buffer it with a high impedance input unity gain stage, and then bias all of my pre-TPA6304 circuitry around the buffered voltage.
Thanks.
