4 / 22 page CS5371 CS5372 4 DS255F3 ANALOG CHARACTERISTICS (Continued) Notes: 7. The upper bandwidth limit is determined by the digital filter. A simple single pole anti-alias filter with a - 3 dB frequency at (MCLK / 256) should be placed in front of each channel. 8. The input voltage range is for the configuration depicted in Figure 3, the System Connection Diagram, and applies to signal frequencies from DC to the stop-band frequency selected in the digital filter. 9. Per channel. All outputs unloaded. All digital inputs forced to VD or GND respectively. 10. In Low Power Mode LPWR = 1, the Master Clock MCLK is reduced to 1.024 MHz. This reduces the oversampled signal bandwidth by a factor of 2. 11. Tested with a 50 Hz 100 mVpp sine wave applied separately to each supply.
