The AD8599ARZ is an Ultralow Distortion Dual Operational Amplifier ideal for use as preamplifiers. The low noise of 1.1nV/√Hz and low harmonic distortion of -120dB (or better) at audio bandwidths give the AD8599 the wide dynamic range necessary for preamplifiers. The excellent slew rate of 14V/μs and 10MHz 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.
