LM6311
Low Noise High Speed Voltage
Feedback Operational Amplifier
General Description
The LM6311 is a low noise voltage feedback operational
amplifier with low distortion. This makes the LM6311 ideal
for signal recovery, high quality video, audio and medical
imaging.
The conventional voltage fedback design makes it easy to
use in standard active filter circuits.
The low distortion makes the LM6311 a good choice for
driving high resolution analog-to-digital converters.
The 50 mA current drive and good capacitive load tolerance
make the LM6311 useful for driving analog-to-digital con-
verters which have switched-capacitor type inputs.
The LM6311 provides low noise and high speed for
a
5V
single supply designs, making it useful for desktop systems
and portable designs.
