NJM2121
HIGH SPEED OPERATIONAL AMPLIFIER WITH SWITCH
■ GENERAL DESCRIPTION
The NJM2121 is a dual operational amplifier of 2-INPUT and
1-OUTPUT with analog switch. The NJM2121 can be used as
analog switch under the condition of GV=0dB, as Switch + Amp
in order that each gain (A or B) can be adjusted independently.
Each amplifier of the NJM2121 has the same electrical
characteristics as the NJM4560.
The NJM2121 is suitable for Audio, Video, Electrical musical
instrument…etc.
