X9319WS8

Digital Potentiometers Overview

The X9319WS8 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a single potentiometer circuit with 100 taps and a resistance value of 10 kOhms. The device utilizes a non-volatile memory architecture to retain the wiper position upon power loss. It operates on a 5V supply voltage and supports serial control interfaces, including Up/Down and Increment/Decrement modes. The component is housed in an 8-SOIC surface-mount package and is designed for linear taper applications within standard operating temperature ranges.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper settings after power cycles
• 100-tap resolution with 10 kOhm total resistance
• Compatible with 3-wire serial or Up/Down control interfaces
• Linear taper characteristic for precise adjustment

Digital Potentiometers Applications

• Audio volume control circuits
• Programmable gain amplifier biasing
• Voltage reference adjustment
• Sensor calibration systems

Digital Potentiometers Procurement Notes

Verify the specific suffix (e.g., Z, I, WT) as it determines environmental compliance, temperature range, and packaging format. Confirm current availability status, as certain variants may be obsolete or end-of-life. Ensure the selected interface mode matches the system controller capabilities.

Digital Potentiometers Selection Notes

Select based on required resistance tolerance and interface type. The 'I' suffix typically denotes industrial temperature range (-40°C to +85°C), while 'Z' indicates commercial range (0°C to +70°C). Verify that the control logic levels are compatible with the host microcontroller. Check for RoHS compliance requirements if applicable to the final assembly.

Digital Potentiometers Part Context

This component belongs to the X9319 series of XDCP devices. It serves as a solid-state replacement for mechanical potentiometers in applications requiring programmable resistance without manual adjustment. The series offers various resistance values and interface options to suit different design constraints.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9319 variants with matching resistance and tap count. Verify pin compatibility and interface protocol before substitution. Consider thermal performance differences between commercial and industrial grade versions.
