GENERAL DESCRIPTION
The AD8599-EP is a very low noise, low distortion op amp ideal
for use as a preamplifier. The low noise of 1.15 nV/√Hz and low
harmonic distortion of −120 dB (or better) at audio bandwidths
give the AD8599-EP the wide dynamic range necessary for
preamplifiers in audio, medical, and instrumentation
applications. The excellent slew rate of 15 V/μs and 10 MHz
gain bandwidth product make the AD8599-EP highly suitable
for medical applications. The low distortion and fast settling
time make the AD8599-EP ideal for buffering high resolution
data converters.
Rev. 0
The AD8599-EP is available in an 8-lead SOIC package. It is
specified over a −55°C to +125°C temperature range.
Additional application and technical information can be found
in the AD8599 data sheet.
