AD8597

Data Sheet Single and Dual, Ultralow Distortion, Ultralow Noise Op Amps AD8597/AD8599 FEATURES Low noise: 1.1 nV/√Hz at 1 kHz Low distortion: −120 dB THD at 1 kHz Input noise, 0.1 Hz to 10 Hz: <76 nV p-p Slew rate: 14 V/μs Wide bandwidth: 10 MHz Supply current: 4.8 mA/amp typical Low offset voltage: 10 μV typical CMRR: 120 dB Unity-gain stable ±15 V operation APPLICATIONS Professional audio preamplifiers ATE/precision testers Imaging systems Medical/physiological measurements Precision detectors/instruments Precision data conversion GENERAL DESCRIPTION The AD8597/AD8599 are very low noise, low distortion operational 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 instrumentation 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.
