NJM2723
High Speed Current Feedback Operational Amplifier
■
General Description
The NJM2723 is a high speed, wide bandwidth and
high output current feedback operational amplifier.
Driving 150Ω load can expand the versatility of several
multimedia applications. Current feedback technology
has wide bandwidth and Low supply current.
With a 75MHz at G=+2, 24MHzat G=+10, high slew
rate of 2000V/µs, second harmonic distortion -65dB
and settling time of 50ns(0.1%) The NJM2723 makes it
ideal for high frequency amplifier, active filter and pulse
amplifier applications.
