PIN CONFIGURATIONS Low noise: 1.1 nV/√Hz at 1 kHz
Low distortion: −120 dB THD at 1 kHz
Input noise, 0.1 Hz to 10 Hz: 2 kΩ is
achieved; the current noise component is larger than the
resistor noise.
100 TOTAL NOISE (nV/ Hz) INPUT VOLTAGE RANGE 10
TOTAL NOISE RESISTOR NOISE
ONLY 1 Output phase reversal occurs in some amplifiers when the input
common-mode voltage range is exceeded. As the common-mode
voltage is moved outside the input voltage range, the outputs of
these amplifiers can suddenly jump in the opposite direction to
the supply rail. This is the result of the differential input pair
shutting down that causes a radical shifting of internal voltages
that results in the erratic output behavior. Rev. F | Page 15 of 20 0.1

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 compensate the other section is in the AN-107 Application Note, Active
Feedback Improves Amplifier Phase Accuracy. The AD8597/AD8599 are the optimum choice for low noise …
