X9241AWVIZ

Digital Potentiometers Overview

The X9241AWVIZ is a quad digital potentiometer IC from the X9241A series, manufactured by Renesas Electronics. It integrates four independent 10 kΩ potentiometers, each featuring 64 taps for linear resistance adjustment. The device utilizes a non-volatile EEPROM to retain wiper settings upon power loss and communicates via a standard two-wire serial interface. It operates on a single 5 V supply with a maximum voltage of 5.5 V and draws approximately 3 mA of current. The component is housed in a 20-lead TSSOP package and supports an industrial temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 10 kΩ digital potentiometers
• Non-volatile memory retains wiper position after power cycle
• Two-wire serial interface (I2C compatible) for control
• Linear taper with 64 tap positions per potentiometer

Digital Potentiometers Applications

• Audio volume and tone control circuits
• Programmable gain amplifiers
• Voltage reference adjustment
• LCD bias voltage generation

Digital Potentiometers Procurement Notes

Verify the specific suffix 'IZ' against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Ensure the selected variant matches the required operating temperature range and packaging type for the target application design.

Digital Potentiometers Selection Notes

Select this component when multiple independent digital resistors are needed in a compact surface-mount package. Verify that the 10 kΩ resistance value and 64-step resolution meet the circuit requirements. Confirm interface compatibility with the host microcontroller's serial ports.

Digital Potentiometers Part Context

This part belongs to the X9241A family of CMOS EEPOTs. Variants within this family differ primarily in resistance values (e.g., 2 kΩ, 50 kΩ), package types (SOIC vs. TSSOP), and temperature grades. The 'WVIZ' suffix indicates the specific 10 kΩ TSSOP version with extended temperature capabilities.

Digital Potentiometers Replacement Considerations

Direct replacements include other X9241A variants with identical pinouts but different resistance or package options, provided electrical parameters match. Cross-family replacements require verification of interface compatibility and physical footprint.
