Looking for a quad opamp rail to rail 3.3v
« on: August 21, 2016, 10:37:26 am »
Hi guys,

I am looking for a cheap, Quad OpAmp chip which can be supplied from a single +3.3V and can amplify up to supply voltage (rail to rail).

Something like LM324 but I think it is not rail to rail?

Thanks!

Still Microchip, if a wider GBW product is needed (10MHz) with lower noise and offset: MCP6024.
About 3dB more expensive, though.
