Basic opamp circuits

This question is asked repeatedly, and Audioguru always posts a really helpful graphic showing inverting and non-inverting opamp circuits for both single and dual supplies.

So to avoid him doing this every time, I'm placing his graphic here, and making this thread 'sticky'.

I've also uploaded the useful TI file sloa058.pdf as the original link has disappeared.

Audioguru's electret mike preamp

Another excellent and frequently posted circuit from Audioguru, I though it was worth posting here as a sticky.
