NJM8901 High Quality Audio J-FET Input Dual Operational Amplifier GENERAL DESCRIPTION PACKAGE OUTLINE The NJM8901 is a high quality audio dual operational Amplifier with JFET technology, strikes a balance between MUSES technology and mass-production technique. The original process tuning and the assembly technology, based on NJM8901E MUSES technology, make excellent sound and absorbing cost (EMP8) increases. The characteristics like Low noise (13nV/Hz), high slew rate (20V/s) and low distortion (0.003% at Av=10) suitable for audio preamplifiers, active filters, and line amplifiers. In addition, taking advantage of the low input bias current that J-FET has, it is suitable for transimpedance amplifier (I/V converter). FEATURES PIN CONFIGLATION Low Noise 13nV/Hz typ. 1.6uVrms typ.
