3 Description

The LM7171 is a high-speed voltage-feedback amplifier that has the slewing characteristic of a current-feedback amplifier, but can be used in all traditional voltage-feedback amplifier configurations. The LM7171 is stable for gains as low as +2 or −1. The device provides a very high slew rate at 4100V/μs and a wide unity-gain bandwidth of 200MHz, while consuming only 6.5mA of supply current. The LM7171 is an excellent choice for video and high-speed signal processing applications, such as HDSL and pulse amplifiers. With 100mA of output current, the LM7171 is 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, which is excellent for ADC/DAC systems. In addition, the LM7171 is specified for ±5V operation for portable applications.
