The X9268 is a low power, 256-tap digitally controlled potentiometer chip from Intersil. It supports 2.7V to 5.5V power supply, has 16 nonvolatile storage registers and supports multi-point storage function. Its maximum standby current is less than 5µA.
The X9268 is a dual‑supply, low‑power digitally‑controlled potentiometer featuring 256 resistor taps, a 2‑wire serial bus for read/write operations, and non‑volatile storage of wiper positions. It offers standby current below 5 µA, power‑on recall, and up to 100 yr data retention.
Typical applications include gain control in audio and RF circuits, voltage trimming in regulators, and sensor signal conditioning. The device is supplied in a 24‑lead SOIC package and is RoHS‑compliant with Pb‑free options.
