The X93256 is a dual digitally controlled potentiometer (XDCP) with features such as dual solid-state potentiometers, individual Up/Down interfaces, 32 wiper tap points per potentiometer, and nonvolatile memory.
The X93256 is a dual digitally controlled potentiometer (XDCP) that includes two resistor arrays, wiper switches, a control section, and non‑volatile memory. Each array contains 31 resistive elements and offers 32 selectable tap points, allowing precise bias, gain, and LCD contrast control.
The document details electrical limits, recommended operating conditions, pin functions, and programming procedures. It also includes package dimensions for the thin‑shrink small‑outline plastic (TSSOP) package and ordering information for various voltage and resistance options.
