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 100MHz unity-gain bandwidth, 3000V/μs slew
rate and 50mA of output current per channel, the LM6172 of-
fers 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 re-
quiring 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
cally Integrated PNP) complementary bipolar process.
