X9241AYSZ

Digital Potentiometers Overview

The X9241AYSZ is a quad digital potentiometer IC from the X9241A series, manufactured by Renesas Electronics. It features four independent potentiometers, each with 64 taps and a resistance value of 2 kOhms. The device utilizes a non-volatile memory architecture to retain wiper settings upon power loss. It operates on a single 5 V supply with a maximum voltage of 5.5 V and draws 3 mA of operating current. The component supports a serial 2-wire interface for control and offers a linear taper. It is housed in a 20-lead SOIC surface-mount package and is rated for an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check for moisture sensitivity handling requirements during storage and assembly. Validate that the specific suffix 'YSZ' corresponds to the SOIC-20 package and industrial temperature grade as documented in the product specification.

Digital Potentiometers Selection Notes

Select this part when a quad digital potentiometer with 2 kOhm resistance and non-volatile retention is required. Ensure the design accommodates the 2-Wire serial interface protocol. Verify that the 20-lead SOIC footprint matches the PCB layout constraints. Confirm that the 5 V supply voltage aligns with the system power rails.

Digital Potentiometers Part Context

The X9241AYSZ belongs to the X9241A family of CMOS EEPOT devices. This series integrates EEPROM technology to provide non-volatile storage for wiper positions. The 'Y' suffix typically denotes the industrial temperature range, while 'S' indicates the SOIC package, and 'Z' often signifies lead-free compliance. Other variants in the family include different resistance values and package types such as TSSOP or PDIP.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include X9241AWSIZT1 (10 kOhm, reel) or X9241AYPZ (2 kOhm, PDIP). Cross-family alternatives may require verification of pin compatibility and interface protocols.
