    I'm looking for an op-amp in SOT23-6 for amplifying audio signals by a maximum gain of (-)2. I need mono only and audio quality is not critical as price and size needs to be optimised. I also would like the op-amp to work from a single 3.3V supply and handle 1Vp-p audio.

    I know I should select a high GBWP of at least double my maximum required (so 2 x 25 kHz = 50 kHz.) But I don't know about what slew rates, offset limits, etc I should choose for audio.

    A casual glance at Microchip shows many results, http://microchip.com/ParamChartSearch/chart.aspx?branchID=11015&mid=11&lang=en&pageId=79

    But there are many more on other websites.

    I'm stuck on which one to choose! Any help would be appreciated.
