BA3812L bias pin from dual rail PS
Hi guys, new here so here's my first Q:
I'm using a Rohm BA3812L graphic EQ chip in a dual rail +/-5V circuit and I'm not sure where to hook up the bias pin 16 (see pic below).
Of course, the normal ground pin (18) will be -5V (vss). so, to be consistent with the circuit, the bias pin would still go through the cap to -5V, but something tells me that it might want to be connected to the true ground in the dual rail.
Which way is correct?
TIA!
side question: I plan to use a Microchip tc1121 charge pump converter for the -5V rail (off of a 7805 +5v ). this pump can clock up to 200khz, well above human audible range... so this should be "quiet" in an audio circuit, correct?
