10 GENERAL DESCRIPTION These amplifiers are ideal for a wide variety of applications.
Audio, filters, photodiode amplifiers, and charge amplifiers, all
benefit from this combination of performance and features.
Additional applications for these amplifiers include portable
consumer audio players with low noise and low distortion that
provide high gain and slew rate response over the audio band at …
