NJM2720
Single Ultra-High speed and Wide Band Operational Amplifier
■
GENERAL DESCRIPTION
The
NJM2720
is single and ultra-high speed and wide band
operational amplifier.
The NJM2720 is 250V/µs slew rate and 150ohm load drive is possible,
at supply voltage of ±2.5V.
The NJM2720 is suitable for video signal processing, video line driver,
video buffer, pulse amplifiers, ADC input buffer, measuring instrument,
and digital communication.
