The LM6172 is a dual, high-speed voltage-feedback amplifier. The device is unity-gain stable and provides excellent dc and ac performance. With a 100MHz unity-gain bandwidth, 3000V/µs slew rate, and 50mA of output current per channel, the LM6172 offers high performance in dual amplifiers, yet only consumes 2.3mA of supply current per channel.

The LM6172 operates on ±15V power supplies for systems requiring large voltage swings, such as ADSL, scanners and ultrasound equipment. The device is also specified for ±5‑V power supplies for low-voltage applications, such as portable video systems.

The LM6172 is built with TI’s advanced complementary bipolar process. See the LM6171 data sheet for a single amplifier with these same features.
