GENERAL DESCRIPTION
The AD8597 is a single, very low noise, low distortion operational 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.
