NJM2112 QUAD OPERATIONAL AMPLIFIER GENERAL DESCRIPTION PACKAGE OUTLINE NJM2112 is low operating voltage ( 1.0V min. ) and low saturation output voltage ( 2.0V at operating voltage 2.5V ) P-P operational amplifier. It is applicable to HANDY TYPE CD, RADIO CASSETTE CD, and PORTABLE DAT, that are digital audio apparatus which require the 5V single supply operation NJM2112M and high output voltage. The NJM2112 is quad operational NJM2112D amplifier. Each amplifier of the NJM2112 has the same electrical characteristic of the NJM2115.
