National P/N LM6172 - Dual High Speed, Low Power, Low Distortion Voltage Feedback Amplifiers
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/s 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.
