LM7171
Very High Speed, High Output Current, Voltage
Feedback Amplifier
General Description
The LM7171 is a high speed voltage feedback amplifier that
has the slewing characteristic of a current feedback ampli-
fier; yet it can be used in all traditional voltage feedback am-
plifier configurations. The LM7171 is stable for gains as low
as +2 or −1. It provides a very high slew rate at 4100V/µs
and a wide unity-gain bandwidth of 200 MHz while consum-
ing only 6.5 mA of supply current. It is ideal for video and
high speed signal processing applications such as HDSL
and pulse amplifiers. With 100 mA output current, the
LM7171 can be used for video distribution, as a transformer
driver or as a laser diode driver.
