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 ±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.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test
conditions, see the Electrical Characteristics.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) Human body model, 1.5kΩ in series with 100pF. Machine Model, 200Ω in series with 100pF.
(4) Continuous short circuit operation can result in exceeding the maximum allowed junction temperature of 150°C.
(5) The maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any ambient
temperature is PD = (TJ(max) TA)/θJA. All numbers apply for packages soldered directly into a PC board.
