NJM2721
Single Ultra-High speed and Wide Band Operational Amplifier
GENERAL DESCRIPTION
The NJM2721 is single and ultra-high speed and wide band
operational amplifier.
The NJM2721 is 500V/µs slew rate and 150ohm load drive is possible,
at supply voltage of ±2.5V.
The NJM2721 is suitable for video signal processing, video line driver,
video buffer, pulse amplifiers, ADC input buffer, measuring instrument,
and digital communication.
