It uses a JFET-input stage that provides extremely high input impedance (10^13 Ohms) and ultra-low input bias current (5pA), critical for audio coupling capacitor circuits where bias current causes DC offsets. The input stage is followed by a folded-cascode voltage gain stage and a Class-AB output stage capable of driving 600Ohm loads. The 8MHz gain-bandwidth product and 20V\/us slew rate ensure the amplifier can reproduce full-scale 20kHz audio signals with minimal distortion. Total harmonic distortion + noise (THD+N) is 0.00008% at 1kHz, making it suitable for professional audio. The FET input eliminates the 1\/f noise corner that bipolar-input op-amps exhibit, providing a flat noise floor across the audio band. The output can swing within 1V of the rails and drive capacitive loads up to 500pF without oscillation.","pin_description":"
