NOTES:
1. All voltages are referenced to ground.
2. Valid for VCC = 2V only.
3. Capacitance values apply at 25°C.
4. Inter-channel matching is used to determine the relative voltage difference in dB between the same
tap position on each potentiometer. The DS1801 is specified for
±0.5 dB inter-channel matching.
5. Tap-to-tap tolerance is used to determine the change in voltage between successive tap positions. The
DS1801 is specified for
±0.25 dB tap-to-tap tolerance.
6. Typical values are for TA =25
°C and nominal supply voltage.
7. See Figure 3.
8. Absolute tolerance is used to determine measured wiper voltage vs. expected wiper voltage as
determined by wiper position. The DS1801 is bounded by a
±1 dB absolute tolerance.
9. Maximum current specifications are based on clock rate and active zero-crossing detection. See
Figure 5 for clock rate vs. current specification.
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.
