The LM6171 is a high-speed, unity-gain-stable voltage-feedback amplifier. The LM6171 offers a high slew rate of 3600 V/µs and a unity-gain bandwidth of 100 MHz while consuming only 2.5 mA of supply current. The LM6171 has very impressive ac and dc performance that is a great benefit for high-speed signal processing and video applications.

The ±15‑V power supplies allow for large signal swings and give greater dynamic range and signal-to-noise ratio (SNR). The LM6171 has a high output current drive, low spurious-free dynamic range (SFDR) and total harmonic distortion (THD), and is an excellent choice for analog-to-digital converter (ADC) and digital-to-analog converter (DAC) systems. The LM6171 is specified for ±5‑V operation for portable applications.
