Note 4

SNR (Signal-to-Noise Ratio) is a ratio of the full-scale output signal level to the noise level with no

signal applied.

Note 5

THD+N (Total Harmonic Distortion plus Noise) is a ratio of the level of the harmonics and noise to the

output signal.

Note 6

PSRR (Power Supply Rejection Ratio) is a measure of the attenuation of a signal on the supply to the

signal at the output.
