AC ELECTRICAL CHARACTERISTICS
NOTES:
1. All voltages are referenced to ground.
2. Valid for V
3. Capacitance values apply at 25°C.
4. Inter-channel matching is used to determine the relative voltage difference in dB between the same
5. Tap-to-tap tolerance is used to determine the change in voltage between successive tap positions. The
6. Typical values are for T
7. See Figure 3.
8. Absolute tolerance is used to determine measured wiper voltage vs. expected wiper voltage as
9. Maximum current specifications are based on clock rate and active zero-crossing detection. See
10. See Figure 7.
11. Standby current levels apply when all inputs are driven to appropriate supply levels.
12. These parameters are characterized and not 100% tested.
13. Valid at 25 C only.
