GENERAL DESCRIPTION
The AD8597/AD8599 are very low noise, low distortion opera-
tional amplifiers ideal for use as preamplifiers. The low noise of
1.1 nV/√Hz and low harmonic distortion of −120 dB (or better)
at audio bandwidths give the AD8597/AD8599 the wide dynamic
range necessary for preamplifiers in audio, medical, and instru-
mentation applications. The excellent slew rate of 14 V/μs and
10 MHz gain bandwidth make them highly suitable for medical
applications. The low distortion and fast settling time make
them ideal for buffering of high resolution data converters.

The AD8597 is available in 8-lead SOIC and LFCSP packages,
while the AD8599 is available in an 8-lead SOIC package. They
are both specified over a −40°C to +125°C temperature range.
The AD8597 and AD8599 are members of a growing series of
low noise op amps offered by Analog Devices, Inc. (see Table 1).
