NOTES:
1. All voltages are referenced with respect to ground.
2. Voltages across the potentiometer terminals (R
3. Inputs UC and DC are internally pulled-up with resistance of 100 k.
4. UC and DC inputs are internally pulled-up to V
5. Active current is specified when the inputs UC or DC are active.
6. Standby current is the current consumed when the UC, DC, and STR inputs are inactive.
7. Input pulse width is the minimum time required for an input to cause an increment or decrement.
8. Repetitive pulse inputs on UC or DC will be recognized as long as they are within 500 milliseconds
9. Input pulse timing has tolerances to ±10%.
10. Capacitance values apply at 25°C.
11. For V
12. If not used STR should be connected to ground.
13. The DS1809 is offered in three values: 10 k, 50 k, and 100 k.
