Renesas Electronics Corporation XDCP™ series ISL22444TFR20Z is a quad-channel digital potentiometer featuring 256 taps per channel and 100k Ohm resistance. This device utilizes an SPI interface for communication and offers a linear taper with ±20% tolerance. Designed for surface mount applications, it is housed in a 20-QFN (5x5) package with an exposed pad. The ISL22444TFR20Z operates across a supply voltage range of ±2.25V to ±5.5V and maintains functionality within an extended temperature range of -40°C to 125°C. Its non-volatile memory ensures configuration retention. Typical wiper resistance is 70 Ohms, with a temperature coefficient of ±45ppm/°C. This component is suitable for applications in industrial automation, consumer electronics, and telecommunications.
