NJM12904
SINGLE SUPPLY DUAL AMPLIFIER
■
GENERAL DESCRIPTION
■
PACKAGE OUTLINE
The NJM12904 is single-supply dual operational amplifier,
which can operate from 2V supply. The features are low
offset voltage, low bias current, and drive TTL or DTL circuit
directly. The package lineup is DIP, DMP and others
compact, which is SON, so that the NJM12904 is suitable
for audio for low voltage operation and any other kind of signal
amplifier.
