LM6171 High Speed Low Power Low Distortion Voltage Feedback Amplifier

Check for Samples: LM6171

FEATURES

DESCRIPTION

The LM6171 is a high speed unity-gain stable voltage

• (Typical Unless Otherwise Noted)

feedback amplifier. It offers a high slew rate of

• Easy-To-Use Voltage Feedback Topology

3600V/μs and a unity-gain bandwidth of 100 MHz

• Very High Slew Rate: 3600V/μs

while consuming only 2.5 mA of supply current. The

LM6171 has very impressive AC and DC

• Wide Unity-Gain-Bandwidth Product: 100 MHz

performance which is a great benefit for high speed

• −3dB Frequency @ A

= +2: 62 MHz

signal processing and video applications.

• Low Supply Current: 2.5 mA

The ±15V power supplies allow for large signal

• High CMRR: 110 dB

swings and give greater dynamic range and signal-to-

• High Open Loop Gain: 90 dB

noise ratio. The LM6171 has high output current

drive, low SFDR and THD, ideal for ADC/DAC

• Specified for ±15V and ±5V Operation

systems. The LM6171 is specified for ±5V operation

for portable applications.
