NOTES:
1. All voltages are referenced to ground.
2. Resistor inputs cannot go below GND by more than 0.5 volts or above V
CC
by 0.5 volts in the positive direction.
3. Capacitance values apply at 25
°
C.
4. –3 dB cutoff frequency characteristics for the DS1806 depend on potentiometer total resistance: DS1806–010;
1 MHz; DS1806–050; 200 KHz, DS1806–100; 100 KHz.

±
10% V
IL
= +0.6V.
7. Absolute Linearity is to used measure expected wiper voltage versus measured wiper voltage as determined by
wiper position. The DS1806 is specified to provide an Absolute Linearity of
+
0.5 LSB.
8. Relative Linearity is used to determine the change in wiper voltage between two adjacent wiper positions. The
DS1806 is specified to provide a relative linearity of
+
0.25 LSB.
9. Standby current levels apply when all inputs are driven to appropriate supply levels.
