X9317WV8IZ

Digital Potentiometers Overview

The X9317WV8IZ is a digitally controlled potentiometer (XDCP) from the XDCP series, manufactured by Renesas Electronics Corporation. It features a single circuit with 100 tap points and a linear resistance taper. The end-to-end resistance is 10 kΩ with a tolerance of ±20%. The device operates on a 5 V supply voltage and utilizes a nonvolatile memory type to retain wiper position data. It employs an Up/Down (U/D), Increment (INC), and Chip Select (CS) interface for control. The component is housed in an 8-TSSOP package with a width of 4.40 mm.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position upon power-up
• 100 tap points with linear resistance taper
• 3-wire serial interface (U/D, INC, CS)
• Low standby current (<5 µA typical)

Digital Potentiometers Applications

• Voltage control circuits
• Current control applications
• Audio volume adjustment
• Gain setting in instrumentation

Digital Potentiometers Procurement Notes

Verify RoHS compliance status as datasheets may vary by revision. Confirm the specific suffix 'Z' indicates lead-free packaging. Check for active manufacturing status versus obsolete variants like X9317WV8. Ensure the 8-TSSOP package matches the PCB footprint requirements.

Digital Potentiometers Selection Notes

Select this model for applications requiring 10 kΩ resistance with 100 discrete steps. Verify that the 5 V supply voltage aligns with the system design. Consider the ±300 ppm/°C temperature coefficient for thermal stability needs. Compare against X9317UV8IZ if 50 kΩ resistance or wider temperature range (-40°C to +85°C) is required.

Digital Potentiometers Part Context

The X9317WV8IZ belongs to the X9317 family of CMOS digitally controlled potentiometers. This family offers solid-state replacement for mechanical potentiometers. Key differentiators include nonvolatile storage and low power consumption. The 'W' suffix typically denotes the TSSOP-8 package variant within the product line.
