NJU7056
Rail-to-Rail Output
Single CMOS Operational Amplifier
■ GENERAL DESCRIPTION
■ PACKAGE OUTLINE
The NJU7056 is a single CMOS operational amplifier that feature
low noise as VNI=15nV/√Hz (at VDD= 5V, f=1kHz). It is tolerant to
RF noise.
The NJU7056 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).
