X9241AYSI

Digital Potentiometers Overview

The X9241AYSI is a quad digital potentiometer IC from the X9241A series, manufactured by Renesas Electronics. It integrates four independent 2 kOhm resistive elements, each featuring 64 taps for precise resistance adjustment. The device utilizes non-volatile EEPROM memory to retain wiper settings upon power loss and communicates via a standard two-wire serial interface. Designed for industrial applications, it operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended temperature range from -40°C to +85°C. The component is housed in a 20-lead SOIC surface-mount package.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 2 kOhm digital potentiometers
• Non-volatile EEPROM storage retains wiper position after power cycle
• Two-wire serial interface (I2C-compatible) for control and data transfer
• Linear taper with ±20% tolerance and 300 ppm/°C temperature coefficient

Digital Potentiometers Applications

• Industrial process control systems requiring multi-channel calibration
• Programmable gain amplifiers in measurement instrumentation
• Voltage reference adjustment in embedded systems
• Audio volume or tone control circuits in consumer electronics

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeits. Confirm RoHS compliance status as indicated in official datasheets. Check moisture sensitivity level (MSL) requirements for proper handling and storage conditions during assembly. Ensure lead-free soldering profiles are compatible with the SOIC-20 package specifications.

Digital Potentiometers Selection Notes

Select this part when multiple independent variable resistors are needed in a compact footprint. The 2 kOhm value suits low-power signal conditioning applications. Consider the 64-tap resolution for moderate precision requirements. Verify that the 5V supply voltage aligns with system power rails. Evaluate thermal performance within the -40°C to +85°C operating range for environmental suitability.

Digital Potentiometers Part Context

The X9241AYSI belongs to the X9241A family of CMOS digital potentiometers. This series offers various resistance values and package options to accommodate different design constraints. The 'AYS' suffix typically denotes the 2 kOhm resistance value and SOIC-20 package variant. The 'IZT1' suffix indicates tape-and-reel packaging for automated assembly processes.

Digital Potentiometers Replacement Considerations

Direct replacements include other X9241A variants with matching resistance and package. Cross-reference with Intersil-branded parts prior to Renesas acquisition. Verify pin compatibility and electrical parameters before substitution. No officially confirmed substitute part numbers are listed in public documentation.
