LM7171QML
Very High Speed, High Output Current, Voltage Feedback
Amplifier
General Description
Features
The LM7171 is a high speed voltage feedback amplifier that
has the slewing characteristic of a current feedback amplifier;
yet it can be used in all traditional voltage feedback amplifier
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 consuming only
6.5 mA of supply current. It is ideal for video and high speed
signal processing applications such as HDSL and pulse am-
plifiers. With 100 mA output current, the LM7171 can be used
for video distribution, as a transformer driver or as a laser
diode driver.

Specified for ±15V and ±5V Operation
Available with radiation guarantee
Operation on ±15V power supplies allows for large signal
swings and provides greater dynamic range and signal-to-
noise ratio. The LM7171 offers low SFDR and THD, ideal for
ADC/DAC systems. In addition, the LM7171 is specified for
±5V operation for portable applications.
The LM7171 is built on National's advanced VIP® III (Verti-
cally integrated PNP) complementary bipolar process.
