X9241AWSIT2

Digital Potentiometers Overview

The X9241AWSIT2 is a quad digital potentiometer IC from the X9241A series, manufactured by Renesas Electronics. It integrates four independent potentiometers, each offering 64 tap positions with a linear taper. The total resistance for each channel is specified at 10 kOhms. The device utilizes a non-volatile memory architecture to retain wiper settings without power and communicates via a serial 2-wire interface. It operates on a single 5 V supply voltage within an industrial temperature range of -40°C to +85°C. The component is housed in a 20-lead SOIC surface-mount package.

Digital Potentiometers Procurement Notes

Verify end-of-life status and availability through authorized distributors. Check for moisture sensitivity levels and reflow soldering requirements during procurement planning. Confirm RoHS compliance details as per specific manufacturing batches.

Digital Potentiometers Selection Notes

Select this component when a quad-channel digital potentiometer with non-volatile storage is required. Ensure the 10 kOhm resistance value and 64-tap resolution meet circuit precision needs. Verify that the 2-wire serial interface is compatible with the host microcontroller's available communication ports.

Digital Potentiometers Part Context

This part belongs to the X9241A family of CMOS EEPOT digital potentiometers. Variants in this series differ primarily in resistance values (e.g., 2 kOhm, 10 kOhm) and packaging options (SOIC, TSSOP). The 'AWS' suffix typically denotes the 10 kOhm resistance value and SOIC-20 package configuration.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9241A variants with matching pinouts and electrical characteristics, such as X9241AWSIZT1 or X9241AWVZT1, provided the package type and resistance tolerance align with the design requirements.
