Overview
The LM6171AIMX/NOPB, produced by Texas Instruments, is a high-speed, unity-gain-stable voltage-feedback amplifier. This device is part of the VIP™ III series and is known for its exceptional ac and dc performance, making it ideal for high-speed signal processing and video applications. The LM6171 offers a high slew rate of 3600 V/μs and a wide unity-gain bandwidth of up to 100 MHz. It operates on low supply current of 2.5 mA and is specified for both ±15-V and ±5-V power supplies, allowing for large signal swings and greater dynamic range and signal-to-noise ratio (SNR).
