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 per-
formance. 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 sup-
ply for low voltage applications such as portable video sys-
tems.
The LM6172 is built with National’s advanced VIP
™
III (Ver-
tically Integrated PNP) complementary bipolar process. See
the LM6171 datasheet for a single amplifier with these same
features.
