The datasheet for the AD5541A DAC (http://www.analog.com/static/imported-files/data_sheets/AD5541A.pdf) recommends using an AD8628 op amp (http://www.analog.com/static/imported-files/data_sheets/AD8628_8629_8630.pdf) to buffer the reference and drive a 10uF capacitor to ground. However, this op amp is very noisy for my application (frequencies up to around 100kHz are important). Does anyone know of a better alternative that is still capable of driving such a large capacitor?
