Notes: 2. See Line Amplifier Gain Compensation (line) for details.
3. Filter response is not tested but is guaranteed by design.
4. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 9-16) have
been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
5. Referenced to a 1 kHz, full-scale sine wave.
6. For Base-Rate Mode, the measurement bandwidth is 0.5465 Fs to 3 Fs.
For High-Rate Mode, the measurement bandwidth is 0.577 Fs to 1.4 Fs.
7. De-emphasis is not available in High-Rate Mode.
