CS5320 AND CS5321 ANALOG CHARACTERISTICS (Continued)

Notes: 9. The upper bandwidth limit is determined by the CS5322 digital filter.

10. This input voltage range is for the configuration shown in Figure 20, the System Connection Diagram,

and applies to signal from dc to f3 Hz. Refer to CS5322 Filter Characteristics for the values of f3.

11. All outputs unloaded. All logic inputs forced to Vdd or GND respectively.

12. LPWR = 0.

13. The CS5321 power dissipation can be reduced under the following conditions:

a) LPWR=1; MCLK=512kHz, HBR=1

b) LWPR=1; MCLK=1.024MHz, HBR=0

14. Characterized with a 100 mVp-p sine wave applied separately to each supply.

* Refer to Parameter Definitions (immediately following pin descriptions at the end of this data sheet).

Specifications are subject to change without notice.
