Hi guys,

I need to design a input rail-to-rail opamp, here is the spec:
1.Rail-to-Rail Input and Output;
2.Gain Bandwidth Product: 1.2MHz
3.7.5mV Typical VOS
4.Operates on 2.0 V to 5.5 V Supplies
5.Input Voltage Range: -0.1 V to +5.6 V with VCC = 5.5 V
6.Low Supply Current: 50¦ÌA

Can anyone pls give me some advice or some references? Thank you.
