wait I meant to say ±2.5V/±1.65V ∆V = 5V/3.3V. Anyhow your AD8221 can take ∆V=5V but since it's not rail-to-rail you'll be looking at a voltage range between 1.9V and 3.9V. That's fine for low-voltage stuff, but if you want to amplify it before it goes into an ADC for maximum resolution or send it to some earphones I'd reconsider your choice of op-amp.
