Hi all,
I have the following specs and I want to design an opamp. The application is that it should be connected at output of DAC and amplify from 1.2(full scale o/p of DAC) to 1.75 V. So will connect it in non inverting configuration..
Vcc=1.8V
Vout=1.75V
Cl = 35pF, Rl = 5Kohms
Idc <60uA
BW=200KHz.
SR is not fixed but can be a very slow Opamp.
I have designed a simple 2 stage Opamp but not getting the full output swing. Should I go for a cascode with class AB ouput?
Any sugestions/pointers with this design..
Thanks
