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.

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.
