PROGRAMMING THE POTENTIOMETER DIVIDER
VOLTAGE OUTPUT OPERATION
The digital potentiometer easily generates an output voltage
proportional to the input voltage applied to a given terminal.
For example, connecting Terminal A to 5 V and Terminal B to
ground produces an output voltage at the wiper that can be any
value from 0 V up to 1 LSB less than +5 V. Each LSB of voltage
is equal to the voltage applied across Terminal A and Terminal B
divided by the 256-position resolution of the potentiometer
divider. The general equation defining the output voltage with
respect to ground for any given input voltage applied to
Terminal A and Terminal B is
VW (Dx) = Dx/256 × VAB + VB
(3)
Operation of the digital potentiometer in the divider mode
results in more accurate operation over temperature. In this
mode, the output voltage is dependent on the ratio of the
internal resistors, not the absolute value; therefore, the drift
improves to 15 ppm/°C.
