NOTES:

1. All voltages are referenced to ground

2. Valid for V

= 5V only.

3. Both PxA and PxG inputs are internally pulled up with a 50KΩ resistance.

4. Capacitance values apply at 25°C.

5. Input pulse width is the minimum time required for an input to cause an increment or decrement of wiper posi-

tion. If the PxA or PxG inputs are held active for longer than 0.8 seconds, subsequent increments or decre-

ments will occur at intervals of 25 ms. Timing tolerances for pushbutton control are specified at 35%.

6. Inter–Channel Matching is used to determine the relative voltage difference in dB between the same position

on each potentiometer. The DS1800 is specified for ±0.25 dB inter channel matching from position 0 to posi-

tion 112 (+20 dB to –27 dB) and ±0.5 dB from position 113 to position 127.

7. Tap–to–Tap tolerance is used to determine the change in voltage between successive tap positions. The

DS1800 is specified for ±0.5 dB tap–to–tap tolerance. From position 0 to position 112 (+20 dB to –27 dB).

From position 113 to position 127, the DS1800 is specified for ±1 dB tap–to–tap tolerance.
