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.
