i'm planning to use tda7295 for our power amp to drive a 8 ohms speaker and have an output of 50w. The datasheet says that the required Vcc is +-30V. Can the 50w output be attained using a single Vcc for the op amp?

Presumably using a 60V single supply, and redesigning the circuit for single supply use.

At least speaker and input coupling capacitors, virtual spilt supply - like anything else really, assuming the chip will allow use in that way.
