DESCRIPTION
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 amplifiers. With
100 mA output current, the LM7171 can be used for
video distribution, as a transformer driver or as a
laser diode driver.
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 Texas Instruments's
advanced VIP™ III (Vertically integrated PNP)
complementary bipolar process.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
