ISL22511WFB8Z - Renesas Electronics

Description: The ISL22511 is a three-terminal digitally-controlled potentiometer (XDCP) implemented by a resistor array composed of 31 resistive elements and a wiper switching network. The ISL22511 features a push-button control, a Shutdown mode, and an industry-leading UTQFN package. The push-button control has individual PU and PD inputs for adjusting the wiper. To eliminate redundancy, the wiper position automatically increments or decrements if one of these inputs is held longer than one second. Forcing both PU and
