GENERAL DESCRIPTION
The AD8597 is a single, 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 AD8597 the wide dynamic range
necessary for preamps in audio, medical, and instrumentation
applications. The AD8597’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 AD8597
make it ideal for buffering of high resolution data converters.
The AD8597 is available in an 8-Lead SOIC and 8-Lead LFCSP
(3x3) packages and is specified over a −40°C to +125°C
temperature range.
