Overview
The LM6171BIM/NOPB, produced by Texas Instruments, is a high-speed, unity-gain-stable voltage-feedback amplifier. This component is designed for high-performance applications requiring fast signal processing and high fidelity. It features a high slew rate of 3600 V/μs and a wide unity-gain bandwidth of up to 100 MHz, making it suitable for various high-speed signal processing and video applications. The LM6171BIM/NOPB operates on both ±15 V and ±5 V power supplies, allowing for large signal swings and a greater dynamic range and signal-to-noise ratio (SNR). This amplifier is also characterized by its low supply current of 2.5 mA, high common-mode rejection ratio (CMRR) of 110 dB, and high open-loop gain of 90 dB.
