The low noise of 1 nV/√Hz and low harmonic distortion of −105 dB (or better) at audio bandwidths give the AD8599 the wide dynamic range necessary for preamps in audio, medical, and instrumentation applications. The AD8599’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 AD8599 make it ideal for buffering of high resolution data converters. The AD8599 is available in an 8-Lead SOIC package and is specified over the −40°C to +125°C temperature range. Rev. 0 Information furnished by Analog Devices is believed to be accurate and reliable.
