SSM2305 Audio Amp Input Range

Hi Harry,

Thank you for the quick reply.

I saw in the datasheet that Vcm range is (Vdd-1) - 1 - (2V with a 4V rail).

As an "audio" amp, I was wondering if Vp-signal is assumed to be about 0.5V:

@ Vcm = 3V, I could go as high as 3.5V +/-

@ Vcm = 1V, I could go as low as 2.5V +/-

I am spoiled by opamps with rail to rail inputs and didn't want to leave any input range on the table.  :-)

Vcm = 1/2 rail, Vp-signal = 1V it is.

Thanks,

Kevin
