ANALOG CHARACTERISTICS
(continued)
Parameter
Combined Digital and On-chip Analog Filter Response - Single Speed Mode
Passband
Notes: 1. Triangular PDF dithered data.
2.
THD+N specifications for 48 kHz sample rates are made over a 20 kHz Bandwidth.
3.
Valid with the recommended capacitor values on FILT+ and CMOUT as shown in Figure 1. Increasing
the capacitance will also increase the PSRR.
4. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 18-25) have
been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
5.
For Single-Speed Mode, the Measurement Bandwidth is 0.5465 Fs to 3 Fs.
For Double-Speed Mode, the Measurement Bandwidth is 0.577 Fs to 1.4 Fs.
