13µA/ch, Rail-to-Rail Output
Quad CMOS Operational Amplifier
NJU7028
■ GENERAL DESCRIPTION
The NJU7028 is a low power, quad CMOS operational
amplifier. It is tolerant to RF noise. The NJU7028 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
NJU7028 is ideal for low-side current sense amplifier.
The very low supply current of the NJU7028 (13µA/ch)
makes it suitable for battery-operated application.
