X9241AYVZT1

Digital Potentiometers Overview

The X9241AYVZT1 is a quad digital potentiometer IC manufactured by Renesas Electronics Corporation. It integrates four independent 64-tap resistive elements with a nominal resistance of 2 kOhms and linear taper characteristics. The device utilizes a non-volatile memory architecture to retain wiper positions upon power loss, ensuring data persistence without external backup. Communication is managed via a standard I2C serial interface, allowing for flexible addressing configurations. It operates within a supply voltage range of 4.5 V to 5.5 V, drawing approximately 3 mA of operating current. The component is housed in a 20-lead TSSOP package suitable for surface-mount PCB assembly.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 2 kOhm digital potentiometers
• Non-volatile memory retains wiper settings across power cycles
• I2C serial interface supports optional address selection for multi-device systems
• Linear taper characteristic with 64 discrete tap positions per channel

Digital Potentiometers Applications

• Precision gain control in audio signal processing circuits
• Voltage reference adjustment in measurement instrumentation
• Bias current setting in analog front-end modules
• Calibration offset trimming in sensor interfaces

Digital Potentiometers Procurement Notes

Verify component status as the X9241AYVZT1 is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Check for moisture sensitivity level (MSL 3) requirements during storage and handling. Validate RoHS compliance status against specific project environmental regulations before procurement.

Digital Potentiometers Selection Notes

Select this component when a quad-channel digital potentiometer with non-volatile retention is required. Ensure the system operates at 5 V with a tolerance of ±10%. Verify that the I2C bus speed and address configuration align with the host controller capabilities. Consider the 2 kOhm resistance value and ±20% tolerance for circuit impedance matching. Evaluate the TSSOP-20 package dimensions for PCB layout constraints.

Digital Potentiometers Part Context

This part belongs to the X9241A series of CMOS EEPROM-based digital potentiometers. The suffix 'Y' indicates an industrial temperature range (-40°C to +85°C), while 'V' denotes the TSSOP-20 package type. The 'ZT1' suffix typically refers to tape-and-reel packaging specifications. This series provides a compact solution for replacing mechanical potentiometers in space-constrained designs requiring programmable resistance.

Digital Potentiometers Replacement Considerations

The X9241AYVIZT1 is identified as a potential upgrade or alternative substitute. Verify pin compatibility and electrical parameter equivalence before substitution. Ensure the replacement maintains the same non-volatile memory functionality and I2C interface protocol.
