X9313ZS

Digital Potentiometers Overview

The X9313ZS is a single-channel digital potentiometer from the XDCP series, manufactured by Renesas Electronics Corporation. It features a resistance value of 1 kOhm with 32 taps and linear taper characteristics. The device utilizes a non-volatile memory architecture to retain wiper settings upon power loss. Control is managed via an Up/Down (U/D), Increment (INC), and Chip Select (CS) interface. It operates on a 5V supply voltage with a typical contact resistance of 40 Ohms and a temperature coefficient of ±300ppm/°C. The component is housed in an 8-SOIC package.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycle
• 32-tap resolution with linear taper for precise adjustment
• Simple Up/Down control interface requiring minimal pins
• 1 kOhm nominal resistance with ±20% tolerance

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in signal conditioning circuits
• Voltage reference trimming in measurement systems
• User interface parameter setting in embedded devices

Digital Potentiometers Procurement Notes

Verify the specific suffix (e.g., Z, ZS, ZST1) against the bill of materials, as these denote packaging or RoHS compliance variations rather than functional differences. Confirm the 8-SOIC package dimensions match the PCB footprint. Check for moisture sensitivity levels if reflow soldering is required. Ensure the 5V supply rail is stable within the specified operating range.

Digital Potentiometers Selection Notes

Select this part when a low-resistance (1 kOhm) digital potentiometer with non-volatile storage is required. The Up/Down interface is suitable for microcontrollers with limited GPIO resources compared to serial interfaces. Verify that the 40 Ohm contact resistance is acceptable for the application's current handling requirements. Consider the ±20% tolerance if high precision is not critical.

Digital Potentiometers Part Context

The X9313ZS belongs to the X9313 family of solid-state digital potentiometers. This family offers various resistance values (1k, 10k, 50k) and packages (SOIC, MSOP). The 'Z' suffix typically indicates lead-free/RoHS compliance in Renesas nomenclature. The device serves as a direct replacement for mechanical potentiometers in applications requiring programmable resistance without moving parts.

Digital Potentiometers Replacement Considerations

X9313ZSZT1 is a verified equivalent with identical electrical specifications but different tape-and-reel packaging. X9313ZST1 is a discontinued version with similar specs but may lack RoHS compliance. Verify pinout compatibility before substituting.
