X9241AYSZT1

Digital Potentiometers Overview

The X9241AYSZT1 is a quad digital potentiometer IC from the Renesas X9241A series, housed in a 20-lead SOIC package. It integrates four independent 2 kOhm resistive elements with linear taper and 64 tap positions per channel. The device utilizes non-volatile memory to retain wiper settings upon power loss and communicates via a standard two-wire serial interface. It operates on a single 5 V supply within an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 2 kOhm digital potentiometers
• Non-volatile memory retains wiper position after power cycle
• Two-wire serial interface for control and data transfer
• Industrial operating temperature range (-40°C to +85°C)

Digital Potentiometers Applications

• Programmable gain amplifiers
• Digital volume control circuits
• Variable voltage reference adjustment

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific moisture sensitivity level (MSL) handling requirements during storage and assembly. Review official datasheets for pinout accuracy and electrical limits before integration.

Digital Potentiometers Selection Notes

Select this model when a quad-channel solution with fixed 2 kOhm resistance is required. Ensure the design supports the 2-wire serial protocol and that the 64-tap resolution meets the application's precision needs. Verify that the SOIC-20 package fits the PCB layout constraints.

Digital Potentiometers Part Context

This component belongs to the X9241A family of CMOS EEPROM digital potentiometers. Variants within the series differ by resistance values (e.g., 10 kOhm, 50 kOhm), package types (SOIC, TSSOP, PDIP), and temperature grades. The 'AY' suffix typically denotes the 2 kOhm resistance value and industrial temperature rating.

Digital Potentiometers Replacement Considerations

Consult the manufacturer's obsolescence notices for potential end-of-life status. Identify cross-referenced part numbers with identical pinouts and electrical specifications if sourcing becomes difficult.
