X9313ZSZT1

Digital Potentiometers Overview

The X9313ZSZT1 is a single-channel digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics Corporation. It features a nominal resistance of 1 kOhms with a linear taper and a tolerance of ±20%. The device contains 32 taps for precise resistance adjustment and utilizes non-volatile memory to retain wiper settings without power. It operates on a 5V supply voltage within a commercial temperature range of 0°C to +70°C. The component communicates via a standard 3-wire serial interface (U/D, INC, CS) and is housed in an 8-SOIC surface-mount package.

Digital Potentiometers Feature Summary

• Non-volatile EEPROM storage retains wiper position after power loss
• 32-tap resolution with linear resistance taper
• Standard 3-wire serial interface for control
• Single circuit configuration in 8-SOIC package

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in signal conditioning circuits
• Voltage reference trimming
• System calibration and offset adjustment

Digital Potentiometers Procurement Notes

Verify RoHS compliance status as datasheet availability may vary; current documentation indicates compliance with ROHS3 standards. Confirm package dimensions against PCB footprint requirements for 8-SOIC (0.154 inch width). Check for recent PCN updates regarding label changes or manufacturing site transfers before finalizing procurement orders.

Digital Potentiometers Selection Notes

Select this part when a low-resistance (1k Ohm) digital potentiometer with non-volatile memory is required. Ensure the application operates within the 0°C to +70°C commercial temperature range. Verify that the 3-wire serial interface is compatible with the host microcontroller's GPIO or SPI pins. Consider the ±20% tolerance if high precision is not critical.

Digital Potentiometers Part Context

This component belongs to the X9313 family of CMOS EEPOTs. It serves as a surface-mount replacement for through-hole variants like the X9313ZSZ. The 'Z' suffix typically denotes the 1k Ohm resistance value, while 'S' indicates the SOIC package and 'T1' specifies tape-and-reel packaging. It is functionally similar to other X9313 variants but distinguished by its specific resistance and package type.

Digital Potentiometers Replacement Considerations

Direct substitute: X9313ZSZT1 (same manufacturer, same specs). Cross-reference with X9313ZST1 if lead-free/RoHS compliance is not strictly required and commercial temperature range suffices.
