Suggest me an extremely low power opamp

low power opamp

can any one suggest a circuit for low power opamp
any architecture which can give extremley low power.

gain bandwidth is just 500hz
slew rate .2v/uS
supply +/- 2.5v or less.
input vtg swing of +/-1v

Re: low power opamp

if u r looking for a low voltage low power opamp use lm358!

BEST!

Re: low power opamp

I suppose two stage opamp architecture is a very good cjoice for your specifications,
a differential stage as the first one, followed by a common-source second stage.......

low power opamp

try MC33272A, MC33274A,
NCV33274A

Re: low power opamp

I think the two stage can meet you spec. The topolog is :
the folded-cascode input stage & class AB output stage;
the general differential input stage & common source sigle amplifier output stage;
the P&N parallel differential input stage & class AB output stage;

or the single folded-cascode amplifier;
or the regulate folded-cascode amplifier;

low power opamp

u also can try ad847 low power opamp.it is just as sameas lm741 but low power and low noise

low power opamp

what is your OP-AMP's gain(f=0)?
