The X9269 is a digitally controlled potentiometer product launched by Xicor. It has dual channels, 256 resistor taps, 0.4% resolution, 2-wire serial interface, low power consumption and other features.
The X9269 integrates two digitally‑controlled potentiometers on a single CMOS IC, offering 256 resistor taps per pot and a 0.4 % resolution. It communicates via a 2‑wire serial bus that supports read, write, and transfer operations, and includes non‑volatile data registers for storing wiper positions.
Key features include a standby current below 5 µA, supply voltage range of 2.7 V to 5.5 V, and packaging options such as 24‑lead SOIC, 16‑lead CSP, and 24‑lead TSSOP. The device is suited for applications like gain control, voltage reference programming, audio volume adjustment, and sensor conditioning.
