SNOSBD8E – MAY 2004 – REVISED MAY 2012
APPLICATION HINTS
The LM833-N is a high speed op amp with excellent phase margin and stability. Capacitive loads up to 50 pF will
cause little change in the phase characteristics of the amplifiers and are therefore allowable.
Capacitive loads greater than 50 pF must be isolated from the output. The most straightforward way to do this is
to put a resistor in series with the output. This resistor will also prevent excess power dissipation if the output is
accidentally shorted.
Noise Measurement Circuit
Complete shielding is required to prevent induced pick up from external sources. Always check with oscilloscope for
power line noise.
