X9317ZV8I-2.7T1

Digital Potentiometers Overview

The X9317ZV8I-2.7T1 is a single-channel digital potentiometer from the Renesas XDCP series, housed in an 8-TSSOP surface-mount package. It features a nominal resistance of 50 kOhms with a linear taper and 100 taps for precise adjustment. The device operates on a serial 3-wire interface (U/D, INC, CS) and utilizes non-volatile memory to retain wiper settings. It supports a supply voltage range of 2.7 V to 5.5 V, with a typical operating current of 50 uA. The component is rated for an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position upon power loss
• Linear taper with 100 discrete tap positions
• Serial 3-wire control interface (U/D, INC, CS)
• Single circuit configuration in 8-TSSOP package

Digital Potentiometers Applications

• Industrial process control systems requiring adjustable gain or reference voltages
• Consumer electronics with programmable volume or brightness controls
• Test and measurement equipment needing remote resistance adjustment

Digital Potentiometers Procurement Notes

Verify the specific suffix 'I-2.7T1' against official Renesas documentation to confirm the extended temperature grade (-40°C to +85°C) and tape-and-reel packaging format. Ensure compatibility with existing PCB footprints for the 8-TSSOP package. Cross-reference part numbers carefully as suffix variations may indicate different temperature ranges or packaging types.

Digital Potentiometers Selection Notes

Select this component when a non-volatile, single-channel digital potentiometer with 50 kOhm resistance is required. The 100-tap resolution provides fine adjustment capabilities suitable for precision applications. Verify that the system's logic levels are compatible with the 3-wire serial interface and that the 2.7 V minimum supply voltage meets the design requirements.

Digital Potentiometers Part Context

This part belongs to the X9317 family of CMOS digital potentiometers manufactured by Renesas Electronics (formerly Intersil). The family offers various resistance values and packaging options. The 'Z' typically denotes a lead-free/RoHS-compliant variant, while 'I' indicates the industrial temperature range. The 'T1' suffix specifies tape-and-reel packaging for automated assembly.

Digital Potentiometers Replacement Considerations

Direct substitutes within the same family include X9317UV8IZ-2.7T1 (industrial temp, tube) or X9317WV8IZ-2.7T1 (different resistance). Verify pinout and electrical specifications before substitution. No other public cross-model substitutes are confirmed.
