NJM14558
DUAL OPERATIONAL AMPLIFIER
■ GENERAL DESCRIPTION
The NJM14558 is a dual operational amplifier, which can
operate from ±2V supply. The features are low offset voltage,
low bias current and low current consumption.
The package lineup is DIP, DMP and others, so that the
NJM14558 is suitable for portable audio and any kind of signal
amplifier.
