X9317TS8I

Digital Potentiometers Overview

The X9317TS8I is a digitally controlled potentiometer (XDCP) from the Renesas X9317 series, manufactured by Renesas Electronics Corporation. It features a single potentiometer configuration with 100 taps and a resistance value of 1k Ohm. The device utilizes a non-volatile memory type to retain wiper settings upon power loss. It operates with a supply voltage of 5V and employs an Up/Down (U/D, INC, CS) serial interface for control. The component is housed in an 8-SOIC package with a linear taper and has a typical temperature coefficient of ±300ppm/°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycle
• 100-tap resolution with 1k Ohm total resistance
• Linear taper characteristic for precise control
• 3-wire serial interface (Up/Down, Increment, Chip Select)

Digital Potentiometers Part Context

The X9317TS8I belongs to the X9317 family of CMOS digital potentiometers. This series is characterized by its non-volatile storage capability and low power consumption. The 'TS' suffix typically denotes the TSSOP-8 package variant within this product line, although specific package verification for the 'I' grade should be confirmed against the official datasheet due to potential nomenclature variations across distributors.

Digital Potentiometers Replacement Considerations

Direct replacements within the X9317 family include variants with different resistance values or packages, such as X9317US8I (50k Ohm, SOIC) or X9317ZS8I (1k Ohm, SOIC). When selecting a substitute, verify that the pinout compatibility and operating voltage range (typically 4.5V to 5.5V) match the original design requirements.
