X9318 is a digitally controlled potentiometer (XDCP) with features such as solid-state potentiometer, 3-wire serial interface, terminal voltage of 0-8V, and 100 wiper tap points. It can be widely used in LCD bias control, DC bias adjustment, gain and offset trim, laser diode bias control, voltage regulator output control, and other applications.
The X9318 is a digitally controlled potentiometer (XDCP) featuring a solid‑state resistor array, non‑volatile memory, and a 3‑wire serial interface. It offers 100 wiper tap points, 99 resistive elements, and can operate as a three‑terminal potentiometer or a two‑terminal variable resistor.
Key features include low‑power CMOS operation, ±20 % end‑to‑end resistance tolerance, 3 mA active current, 1 mA standby current, and a data‑retention capability of 100 years. The device is supplied in 8‑lead SOIC and DIP packages and is rated for up to +8 V terminal voltage.
