X9317US8I-2.7T1

Digital Potentiometers Overview

The X9317US8I-2.7T1 is a single-channel digital potentiometer from the Renesas XDCP series, housed in an 8-TSSOP surface-mount package. It features a total resistance of 50 kOhms with a linear taper and 100 tap positions for precise adjustment. The device operates on a supply voltage range of 2.7V to 5.5V and utilizes non-volatile memory to retain wiper settings upon power loss. Control is managed via a standard Up/Down (U/D), Increment (INC), and Chip Select (CS) serial interface. Key electrical parameters include a typical contact resistance of 200 Ohms and a temperature coefficient of ±300ppm/°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycle
• Single circuit configuration with 100 discrete taps
• Linear resistance taper for consistent adjustment curves
• Low power consumption with 50uA operating current

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in signal conditioning circuits
• Voltage reference setting in measurement systems
• Calibration of sensor bias points

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors as counterfeits exist. Confirm RoHS compliance status as older batches may not meet current environmental standards. Check for lead-free marking on the package top. Ensure storage conditions prevent moisture damage despite MSL rating 1 classification.

Digital Potentiometers Selection Notes

Select this part when non-volatile memory is required to maintain setpoints without battery backup. Compare contact resistance specifications against load requirements. Verify that the 50kOhm total resistance fits within the target circuit's impedance constraints. Ensure the 8-TSSOP footprint matches the PCB layout design rules.

Digital Potentiometers Part Context

This component belongs to the X9317 family of CMOS digital potentiometers. It serves as a solid-state replacement for mechanical potentiometers in applications requiring remote or automated adjustment. The series offers various resistance values and packaging options to suit different industrial and consumer electronics designs.

Digital Potentiometers Replacement Considerations

Direct substitute: X9317US8IZ-2.7T1. Verify pin compatibility and electrical parameter equivalence before substitution. Check if the 'Z' suffix indicates RoHS compliance changes.
