GENERAL DESCRIPTION
The AD8599 is a dual, very low noise, low distortion opera-
tional amplifier ideal for use as a preamplifier. The low noise of
1 nV/√Hz and low harmonic distortion of −105 dB (or better)
at audio bandwidths give the AD8599 the wide dynamic range
necessary for preamps in audio, medical, and instrumentation
applications. The AD8599’s excellent slew rate of 16 V/μs and
10 MHz gain bandwidth make it highly suitable for medical
applications. The low distortion and settling time of the AD8599
make it ideal for buffering of high resolution data converters.
The AD8599 is available in an 8-Lead SOIC package and is
specified over the −40°C to +125°C temperature range.
