AD5247 THEORY OF OPERATION The AD5247 is a 128-position, digitally-controlled variable resistor (VR) device. An internal power-on preset places the wiper at midscale during power-on, which simplifies the default condition recovery at power-up. PROGRAMMING THE VARIABLE RESISTOR Rheostat Operation The ...

Typical device-to-device matching is process lot dependent and can vary ±30%. Because the resistance element is processed in thin film technology, the change in R temperature has a very low 45 ppm/°C temperature coefficient. PROGRAMMING THE POTENTIOMETER ...

AD5247 LEVEL SHIFTING FOR BIDIRECTIONAL INTERFACE While most legacy systems can be operated at one voltage, a new component can be optimized at another voltage. When two systems operate the same signal at two different voltages, proper level shifting is ...

LAYOUT AND POWER SUPPLY BYPASSING It is good practice to employ a compact, minimum lead-length layout design. The leads to the inputs should be as direct as pos- sible with minimum conductor length. Ground paths should have low resistance and ...
