Yes, that's correct. In case you take this route, recommended, you can
replace all capacitors by shorts, they're there only to block DC
levels from getting in each other's way. VREF and GRND should be
connected together. It might be an idea to keep C1 and C8 to block
external DC levels from getting into the circuit.

Whatever you do, DO NOT try to use the +B supply for this circuit.
