Renesas Electronics Corporation Digital Potentiometers X9241AMS

The X9241AMS is a quad digital potentiometer from Quarktwin Technology Ltd., featuring four independently controlled potentiometers integrated into a single CMOS microcircuit. Each potentiometer offers 64 taps and can be configured as either a three-terminal potentiometer or a two-terminal variable resistor, making it suitable for various applications such as control, parameter adjustments, and signal processing. The device operates via a 2-wire I¬=C interface, allowing for direct read and write access to its registers. It includes a volatile Wiper Counter Register (WCR) and four non-volatile Data Registers (DR0 to DR3) for storing wiper positions. The X9241AMS supports terminal voltages of +5V and -3.0V, and it is available in multiple resistor values: 2kOc, 10kOc, and 50kOc, with the option for cascading to achieve higher resistance values. This product is designed for low power consumption and high reliability, with an endurance rating of 100,000 data changes per bit per register and a data retention period of up to 100 years. It is offered in a 20-lead SOIC package and is RoHS compliant.
