OPERATIONAL AMPLIFIER WITH SWITCH
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJM2120 is a dual operational amplifier of 2-INPUT and
1-OUTPUT with analog switch.The NJM2120 can be used as
analog switch under the condition of G
V
=0dB,as Switch + Amp
in order that each gain (A or B) can be adjusted
independently.Each amplifier of the NJM2120 has the same
electrical characteristics as the NJM4558.
The NJM2120 is suitable for Audio,Video,Electrical musical
instrument…etc.
