X9241AWSIT1

Digital Potentiometers Overview

The X9241AWSIT1 is a quad CMOS electrically erasable potentiometer (EEPOT) from the Renesas X9241A series. It integrates four independent digital potentiometers, each featuring 64 tap positions and a resistance value of 10 kOhms. The device utilizes a linear taper and operates on a single 5 V supply with a typical current consumption of 3 mA. Communication is managed via a serial 2-wire interface. The wiper position data is stored in non-volatile memory, ensuring retention without power. It is housed in a 20-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 10 kOhm digital potentiometers
• Non-volatile wiper storage retains settings after power loss
• Serial 2-wire interface for control and data transfer
• Linear taper characteristic with 64 discrete tap positions per channel

Digital Potentiometers Applications

• Programmable gain amplifiers requiring precise resistance adjustment
• Voltage reference trimming in measurement systems
• Digital volume control in audio processing circuits
• Calibration of sensor signal conditioning paths

Digital Potentiometers Procurement Notes

Verify the specific suffix IT1 against official Renesas documentation to confirm tape-and-reel packaging and exact pinout compatibility. Ensure the selected variant matches the required 10 kOhm resistance and SOIC-20 package dimensions for PCB integration. Cross-reference the manufacturer part number with authorized distributors to confirm current production status and availability.

Digital Potentiometers Selection Notes

Select this component when a quad-channel solution with non-volatile memory is required. The 10 kOhm resistance value suits applications needing moderate impedance levels. Verify that the system voltage aligns with the 4.5 V to 5.5 V operating range. Consider the 2-wire serial interface constraints if multiple devices share the same bus lines in the design.

Digital Potentiometers Part Context

This part belongs to the X9241A family of quad EEPROM-based digital potentiometers. The 'AWS' designation typically indicates the 10 kOhm resistance value and commercial/industrial temperature grade variants within the SOIC package line. Other suffixes may denote different resistance values or package types such as TSSOP.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9241A variants with identical pinouts but potentially different resistance values or packages, such as X9241AWVIZT1. Verify functional equivalence regarding interface protocol and memory type before substitution.
