MICRO-POWER OPERATIONAL AMPLIFIER
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJM4250 is extremely versatile programmable
monolithic operational amplifiers. A single external master bias
current setting resistor programs the input bias current, input
offset current, quiescent power consumption, slew rate, input
noise, and the gain-bandwidth product. The device is a truly
general purpose operational amplifier.
■ FEATURES
● Operating Voltage ( ±1V~±18V )
● Low Operating Current ( 0.1mA max. )
● Programmable monolithic OP-Amp
● Very Low Power Consumption
● Package Outline DIP8,DMP8,SSOP8
● Bipolar Technology
