NJU7027
13μA/ch, Rail-to-Rail Output
Dual CMOS Operational Amplifier
■
GENERAL DESCRIPTION
The NJU7027
is a low power, dual CMOS operational amplifier.
It is tolerant to RF noise. The NJU7027 can operate from a
single-supply voltage of +1.8V to +5.5V. In addition, this
amplifier features Rail-to-Rail output and low input bias current
(1pA). Because of these features, the NJU7027 is ideal for low
side current sense amplifier. The very low supply current of the
NJU7027 (13μA/ch) makes it suitable for battery-operated
application.
