DIGIPOT, 256 PSTNManufacturer: Intersil
Categories: Digital Potentiometers
Quality Control: Learn More
The Intersil ISL22444UFV20Z-TK is a 50k Ohm, 4-circuit digital potentiometer from the XDCP™ series. This device features 256 discrete tap positions per channel, offering precise resistive element adjustment. Communication with the ISL22444UFV20Z-TK is managed via a serial peripheral interface (SPI). The non-volatile memory retains programmed wiper positions, ensuring consistent operation across power cycles. Designed for surface mounting, it utilizes a 20-TSSOP package. Applications for this component span industrial automation, consumer electronics, and test and measurement equipment where accurate and repeatable voltage or current division is critical. The device operates within a voltage range of ±2.25V to ±5.5V and maintains a typical temperature coefficient of ±45ppm/°C over an operating temperature range of -40°C to 125°C.
