NJM2123 DUAL OPERATIONAL AMPLIFIER WITH SWITCH GENERAL DESCRIPTION PACKAGE OUTLINE The NJM2123 is a operational amplifier with analog switch ( 2 circuit of 2-input/1-output ). It is applicable to the audio part for Video ( VTR,LD) and the Car-stereo. The NJM2123 has the same electrical characteristic of the NJM2112,and is low saturation output type. The mode of switch is improved from the current control type NJM2123D NJM2123M ( NJM2120:1 circuit of 2-input/1-output ) to the voltage control type.So,it is easy to use.
