LM6171 High Speed Low Power Low Distortion Voltage Feedback Amplifier
General Description
The LM6171 is a high speed unity-gain stable voltage feed­back amplifier. It offers a high slew rate of 3600V/µs and a unity-gain bandwidth of 100 MHz while consuming only 2.5 mA of supply current. The LM6171 has very impressive AC and DC performance which is a great benefit for high speed signal processing and video applications.
The
±
15V power supplies allow for large signal swings and give greater dynamic range and signal-to-noise ratio. The LM6171 has high output current drive, low SFDR and THD, ideal for ADC/DAC systems. The LM6171 is specified for
±
5V operation for portable applications.
The LM6171 is built on National’s advanced VIP
™
III (Verti-
cally Integrated PNP) complementary bipolar process.

Note 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.
Note 2: Human body model, 1.5 kΩ in series with 100 pF. Note 3: Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150˚C. Note 4: The maximum power dissipation is a function of T
J(max)
, θJA, and TA. The maximum allowable power dissipation at any ambient temperature is P
D
=
(T
J(max)−TA
)/θJA. All numbers apply for packages soldered directly into a PC board.
Note 5: Typical Values represent the most likely parametric norm. Note 6: All limits are guaranteed by testing or statistical analysis. Note 7: Large signal voltage gain is the total output swing divided by the input signal required to produce that swing. For V
S
=
±

OUT
=

S
=

V
OUT
=

Note 8: The open loop output current is the output swing with the 100Ω load resistor divided by that resistor. Note 9: Slew rate is the average of the rising and falling slew rates. Note 10: Differential gain and phase are measured with A
