LM6172 Dual High Speed, Low Power, Low Distortion, Voltage Feedback Amplifiers

General Description

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

The LM6172 operates on

±

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. See the LM6171 datasheet for a single amplifier with these same features.
