AD8597/AD8599
The AD8597/AD8599 are the optimum choice for low noise
performance if the source resistance is kept < 1 kΩ. At higher
values of source resistance, optimum performance with respect
to only noise is obtained with other amplifiers from Analog
Devices. Both voltage noise and current noise need to be consi-
dered. For more information on avoiding noise from grounding
problems and inadequate bypassing, see the AN-345 Application
Note, Grounding for Low- and High-Frequency Circuits. For

general noise theory with extensive calculations, see the
AN-358 Application Note, Noise and Operational Amplifier
Circuits. A good selection table for low noise op amps can
be found in AN-940 Application Note, Low Noise Amplifier
Selection Guide for Optimal Noise Performance. An interesting
note on using one section of a monolithic dual to phase compen-
sate the other section is in the AN-107 Application Note, Active
Feedback Improves Amplifier Phase Accuracy.
