NOTES:
1. All inputs; UV, DC, and D are internally pulled up with a resistance of 100kΩ.
2. Input logic levels are referenced to -V.
3. I
4. Input leakage applies to contact inputs UC and DC and digital input (D).
5. Wiper current and rheostat currents are the maximum currents which can flow in the resistive
6. Capacitance values apply at 25°C.
7. Input pulse width is the minimum time required for an input to cause an increment or decrement. If
8. Repetitive pulsed inputs on UC, DC, or D will be recognized as long as the pulse repetition occurs
9. Idle state supply current is measured with no pushbutton depressed and with the wiper. R
10. Maximum time required for the Dallastat to determine single or dual pushbutton operation after input
11. Absolute linearity is used to determine wiper voltage versus expected voltage as determined by wiper
12. Relative linearity is used to determine the change in voltage between successive tap positions.
13. -3 dB cutoff frequency characteristics for the DS1669 depend on potentiometer total resistance:
14. Valid at 25°C only.
elements.
the UC, DC or D input is held active for longer than 1 second, subsequent increments or decrements
will occur on 100 ms intervals until the inputs UC, DC, and/or D is released to V
within 1 second of each other. Pulses occurring faster than 1 ms apart may not be recognized as
individual inputs but can be interpreted a constant input.
