Digital Potentiometer, 256 Steps, Serially Interfaced 10kΩ

The AS1500 is a Digital Potentiometer with 256 programmable steps. The values of the resistor CAN be controlled via 3 wire serial Interface capable to handle programming rates up to 10MHz. The AS1500 is available in four different resistor values. The AS1500 incorporates a 10k, the AS1501 a 20k, the AS1502 a 50k and the AS1503 a 100k fixed resistor. The wiper contact taps the fixed resistor at points determined by the 8-bit digital code word. The resistance between the wiper and the endpoint of the resistor is linear. The switching action is performed in a way that no glitches occur. Furthermore the AS1500 includes a shutdown mode, where it consumes less than 5A. The AS1500 is available in an 8-pin SOIC package.
