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 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
supply for low voltage applications such as portable video
systems.
The LM6172 is built with National’s advanced VIP
tically Integrated PNP) complementary bipolar process. See
the LM6171 datasheet for a single amplifier with these same
features.
