Renesas Electronics Corporation's XDCP™ series ISL22444TFV20Z is a quad-channel digital potentiometer offering 256 discrete tap positions per channel. This device provides a nominal resistance of 100k Ohms with a ±20% tolerance and a linear taper. The interface utilizes a 3-wire SPI protocol for efficient command execution. Designed for surface mounting within a 20-TSSOP package, it operates across a wide temperature range of -40°C to 125°C. Key applications include industrial control systems, audio and video equipment, and general-purpose analog circuit adjustment. The non-volatile memory retains programmed wiper positions, enhancing system reliability. Typical wiper resistance is 70 Ohms, with a temperature coefficient of ±45ppm/°C. The device supports a supply voltage range of ±2.25V to 5.5V.
