NJM2140
LOW SATURATION DUAL OPERATIONAL AMPLIFIER
■
GENERAL DESCRIPTION
The NJM2140 is a low supply voltage(±1.0V MIN) and low
saturation output voltage(±2.0Vp-p at supply voltage ±2.5V)
operational amplifier. It is applicable to portable CD, radio
cassette CD, and portable DAT, that are audio apparatus which
require the 5V single supply operation and high output voltage.
