The LM6172 is a dual high speed 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 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 TI's advanced VIP III
(Vertically Integrated PNP) complementary bipolar
process. See the LM6171 datasheet for a single
amplifier with these same features.
