X9317ZS8IT1

Digital Potentiometers Overview

The X9317ZS8IT1 is a single-channel digital potentiometer from the XDCP series, manufactured by Renesas Electronics Corporation. It features a resistance value of 1 kOhm with 100 taps and a linear taper. The device utilizes non-volatile memory to retain wiper settings upon power loss. It operates on a 5V supply voltage with a typical contact resistance of 200 Ohms and a temperature coefficient of ±300ppm/°C. The component is housed in an 8-SOIC package (0.154" width) and supports surface-mount installation.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycle
• 1 kOhm resistance with 100 discrete taps
• Linear taper configuration for precise control
• 3-wire serial interface (U/D, INC, CS)

Digital Potentiometers Applications

• Audio volume control circuits
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming

Digital Potentiometers Procurement Notes

Verify component status as the X9317ZS8IT1 is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure the specific suffix matches the required 8-SOIC package and industrial temperature range specifications before procurement.

Digital Potentiometers Selection Notes

Select this component when a compact, non-volatile digital potentiometer with 1 kOhm resistance is required. The 8-SOIC package suits space-constrained PCB designs. Verify that the 5V operating voltage and linear taper align with the circuit requirements. Consider the ±20% tolerance and contact resistance parameters for precision applications.

Digital Potentiometers Part Context

This part belongs to the X9317 family of CMOS digital potentiometers. Variants within the family differ primarily in resistance values (e.g., 1k, 10k, 50k), package types (SOIC, TSSOP, MSOP), and temperature ranges. The ZS8IT1 specifically denotes the 1kOhm version in an SOIC-8 tape and reel package.

Digital Potentiometers Replacement Considerations

Direct replacements may include other X9317 variants with matching resistance and interface, such as X9317ZS8IZ. Cross-reference pinouts and electrical characteristics carefully. Alternative manufacturers offer similar digital potentiometers, but pin compatibility and non-volatile functionality must be verified.
