Hot-selling and scarce ISL90728UIE627Z-TK Digital Potentiometer 50k Ohm 1 Circuit 128 Taps I2C Interface SC-70-6 spot stock

Product Descriptions

The Intersil ISL90727 and ISL90728 are digitally controlledpotentiometers (XDCP™). Each device consists of a resistorarray, wiper switches, and a control section . The wiperposition is controlled by an I2 C Bus™.

​

The potentiometer is implemented by a resistor arraycomposed of 127 resistive elements and a wiper switchingnetwork . Between each element and at either end are tappoints accessible to the wiper terminal . The position of thewiper element is controlled by the SDA and SCL inputs .
