ISL22313WFU10Z

Digital Potentiometers Overview

The ISL22313WFU10Z is a single-channel digital potentiometer IC manufactured by Renesas Electronics. It features a resistance value of 50 kOhms with 256 tap positions and utilizes a linear taper for precise adjustment. The device incorporates non-volatile memory to retain the wiper setting upon power loss. Communication is handled via a serial I2C interface, supporting operating supply voltages of 2.5 V, 3.3 V, and 5 V. It operates within a temperature range of -40°C to +125°C and is housed in an MSOP-10 surface-mount package.

Digital Potentiometers Feature Summary

• Single channel digital potentiometer with 50 kOhm resistance and 256 taps
• Non-volatile memory retains wiper position after power cycle
• I2C serial interface for control and data transfer
• Wide operating voltage range: 2.5 V, 3.3 V, or 5 V

Digital Potentiometers Applications

• Industrial process control systems requiring adjustable gain or reference voltages
• Consumer electronics with user-adjustable settings stored in non-volatile memory
• Automotive instrumentation panels needing durable, solid-state variable resistors

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors as counterfeits exist. Confirm RoHS compliance status for environmental regulations. Check for End-of-Life (EOL) notifications from Renesas to ensure long-term availability. Validate the specific suffix 'W' against official datasheets to confirm any unique packaging or material specifications compared to standard variants.

Digital Potentiometers Selection Notes

Select this component when a single-channel, non-volatile digital potentiometer is required. Ensure the system supports I2C communication protocols. Verify that the 50 kOhm resistance and 256-step resolution meet the application's precision requirements. Confirm compatibility with the target supply voltage (2.5V, 3.3V, or 5V) and the MSOP-10 footprint constraints.

Digital Potentiometers Part Context

This part belongs to the ISL22313 series of digital potentiometers. It shares core functionalities with other members of the family but differs in package type and specific suffix designations. The series is designed for applications replacing mechanical potentiometers where reliability and programmability are critical.

Digital Potentiometers Replacement Considerations

Direct replacements may include other ISL22313 variants with different packages (e.g., SOIC) if pinout compatibility allows. Cross-reference with newer Renesas digital potentiometer families for pin-compatible upgrades, ensuring I2C address and command set compatibility.
