This is Intersil X9110 1024-Tap/SPI Bus Single Digitally-Controlled (XDCP™) Potentiometer datasheet.
The Intersil X9110 integrates a single digitally‑controlled potentiometer (XDCP) on a CMOS IC. It offers 1024 resistor taps for 10‑bit resolution, a SPI serial interface, and both volatile and non‑volatile registers for storing wiper positions. The device operates from 2.7 V to 5.5 V (system VCC) with analog supplies of –5 V to +5 V and a typical wiper resistance of 40 Ω at 5 V.
Typical applications include gain control for amplifiers, programmable references, audio volume control, offset trimming, and sensor signal conditioning. The datasheet provides pin descriptions, functional diagrams, instruction sets, and package dimensions for the 14‑lead TSSOP version.
