NJM2082
DUAL J-FET INPUT OPERATIONAL AMPLIFIER
■
GENERAL DESCRIPTION
The NJM2082 is JFET input dual operational amplifiers.The
NJM2082 features low input offset and bias current,high input
impedance.The NJM2082 ideally suits for fast integrator,DA
converter,sample & hold and audio applications.The NJM2082
is improved version of the NJM082.
