X9241AUVIT1

Digital Potentiometers Overview

The X9241AUVIT1 is a quad digital potentiometer from the Renesas XDCP series, housed in a 20-pin TSSOP package. It integrates four independent potentiometers with non-volatile memory for wiper position storage. Each channel offers 64 tap positions and utilizes an I2C serial interface for control. The device operates on a single 5V supply and features linear taper characteristics with a typical resistance tolerance of ±20%. It is designed for surface-mount applications within an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 64-tap digital potentiometers
• Non-volatile EEPROM memory retains wiper settings upon power loss
• I2C compatible serial interface for addressable control
• Linear taper characteristic with ±20% resistance tolerance

Digital Potentiometers Applications

• Programmable gain amplifiers in signal conditioning circuits
• Digital volume control in audio processing systems
• Voltage reference adjustment in power management modules
• Sensor bias calibration in measurement instrumentation

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as older batches may not meet current environmental standards. Validate that the specific suffix corresponds to the required tape-and-reel packaging format for automated assembly processes.

Digital Potentiometers Selection Notes

Select this component when a quad-channel solution with non-volatile retention is required. Ensure the system voltage aligns with the specified 5V operating range. Verify that the PCB layout supports the 20-TSSOP footprint dimensions and thermal requirements for the intended operating environment.

Digital Potentiometers Part Context

This part belongs to the X9241A family of CMOS digital potentiometers. Variants within the family differ primarily by resistance values (e.g., 2kΩ, 10kΩ, 50kΩ) and package types (TSSOP, SOIC, PDIP). The 'U' suffix typically denotes the TSSOP package, while 'VI' indicates industrial temperature grading and RoHS compliance.

Digital Potentiometers Replacement Considerations

Direct replacement options include other members of the X9241A family with identical pinouts and functionality but different resistance values or package styles, such as X9241AWSIZT1 or X9241AWVIZT1.
