Intersil X93255 is a dual digitally controlled potentiometer (XDCP) with independent Up/Down interfaces and nonvolatile memory. Each potentiometer consists of 31 resistive elements and a wiper switching network, and can be used in various applications such as bias and gain control, LCD contrast adjustment, etc.
The X93255 is a dual digitally controlled potentiometer (XDCP) that includes two resistor arrays, wiper switches, a control section, and non‑volatile memory. Each potentiometer offers 32 tap points, 31 resistive elements, and independent Up/Down interfaces for precise bias, gain, and LCD contrast control.
The datasheet details electrical limits, recommended operating conditions, pin descriptions, programming sequences, and package dimensions (14‑lead TSSOP). It also lists endurance of 200 000 data changes per bit, 100‑year data retention, and typical active and standby currents.
