Total Distortion, Including Quantizing Distortion
The signal-to-total distortion ratio will exceed the limits shown in Figure 5 for either path when the input signal is a
sine wave signal of frequency 1014 Hz.
Improved distortion at lower levels in LSSGR applications can be obtained by proper selection of the GX and GR
ranges.
