SINGLE-SUPPLY OPERATIONAL AMPLIFIER
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJM2125 is a single-supply operational amplifier of small
surface mount package.
The features of single-supply operation, low operating voltage
( minimum 2.7V ) and small package are most suitable for
portable items.
■ FEATURES
● Single-Supply Operation
● Low Operating Voltage ( +2.7V~20V )
● Low Operating Current ( 1.0mA typ. )
● Slew Rate ( 1.2V/µs typ. )
● Small Package ( MTP5,FFP12)
● Bipolar Technology
