LM6171 High Speed Low Power Low Distortion Voltage Feedback Amplifier
May 1998
LM6171
High Speed Low Power Low Distortion Voltage Feedback
Amplifier
General Description
The LM6171 is a high speed unity-gain stable voltage feed-
back amplifier. It offers a high slew rate of 3600V/碌s 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
鹵
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
鹵
5V operation for portable applications.
The LM6171 is built on National鈥檚 advanced VIP
鈩?/div>
III (Verti-
cally Integrated PNP) complementary bipolar process.
