Dual Boost Amplifier
■
■■
■ GENERAL DESCRIPTION
The NJM2160B is a dual boost amplifier designed for car
audio system. It expands the frequency characteristics by
high slew rate.
It can swing 14V peak-to-peak output voltage at 9V. It
consists of two channel non-inverting amplifier with the gain
of 8dB.
It is suitable for car audio system and other boost amplifier
system.
