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 (Vertically Integrated
PNP) complementary bipolar process.
