The X9314 is a single-ended digitally controlled potentiometer from Intersil, which uses a solid-state non-volatile resistive array, and is ideal for digitally controlled resistance trimming. The X9314 is composed of 31 resistive elements. There are tap points accessible to the wiper element between each element and at either end. The position of the wiper element is controlled by the CS, U/D and INC inputs. The position of the wiper can be stored in non-volatile memory and then be recalled upon a subsequent power-up operation. The XDCP can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of applications including control, parameter adjustments, and signal processing.
The Intersil X9314 is a solid‑state nonvolatile potentiometer designed for digitally controlled resistance trimming. It offers 32 taps, a 10 kΩ end‑to‑end resistance, and a three‑wire up/down serial interface with non‑volatile storage of the wiper position.
The device is available in 8‑lead MSOP, SOIC, and PDIP packages and operates from 3 V to 5.5 V over a temperature range of –40 °C to +85 °C. Detailed electrical specifications, pin functions, and timing parameters are provided for designers.
