NJM8901
High Quality Audio
J-FET Input Dual Operational Amplifier
■GENERAL DESCRIPTION
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
MUSES technology, make excellent sound and absorbing cost
increases.
The characteristics like Low noise (13nV/√Hz), high slew rate
(20V/µs) 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).
