Texas Instruments LM6172 Voltage Feedback Amplifier
Texas Instruments LM6172 Voltage Feedback Amplifier is a dual high-speed, low power, low distortion, voltage feedback amplifier. It is unity-gain stable and provides excellent DC and AC performance. With 100MHz unity-gain bandwidth, 3000V/μs slew rate, and 50mA of output current per channel, the LM6172 offers high performance in dual amplifiers; yet it only consumes 2.3mA of supply current each channel.
The Texas Instruments LM6172 operates on a ±15V power supply for systems requiring large voltage swings, such as ADSL, scanners, and ultrasound equipment. It is also specified at ±5V power supply for low voltage applications such as portable video systems. The LM6172 is built with National's advanced VIP III (Vertically Integrated PNP) complementary bipolar process.
