Post by thread:[EE] Looking for opamp

Hi guys, I'm looking for an easy to find op amp, capable of rail to rail swing using a single positive supply (0 to +5v) as for the bandwidth, the signal to be amplified is <= 1MHz. I really need this to be an easy to find part - that would rule out anything made by Maxim =) Does anybody know of any readly available opamps that fit those requirements? Thanks. -Mario

Cheap, available in single, dual, and quad. To me, "readily available" means Digi-Key's got 'em in stock.

As an example, the TLV2370's definition of rail to rail is 0.1V to 4.9V @ VCC = 5V and 25degC (See VOH and VOL specs). Paul > signal to be amplified is <= 1MHz.

Awesome. And it's cheap too.
