X9317US8-2.7T1

Digital Potentiometers Overview

The X9317US8-2.7T1 is a digitally controlled potentiometer (XDCP) from the Renesas XDCP series, manufactured by Renesas Electronics Corporation. It features a single potentiometer circuit with a total resistance of 50 kOhms and 100 taps for precise adjustment. The device utilizes non-volatile memory to retain wiper settings upon power loss. It operates on a supply voltage range of 2.7V to 5.5V and employs a serial 3-wire interface (Up/Down, Increment, Chip Select). The component is housed in an 8-SOIC surface-mount package.

Digital Potentiometers Feature Summary

• Single-channel digital potentiometer with 50 kOhm total resistance and 100 adjustable taps.
• Non-volatile memory retains wiper position after power cycle.
• Operates within a 2.7V to 5.5V supply voltage range.
• Serial 3-wire interface compatible with standard microcontrollers.

Digital Potentiometers Applications

• Volume control in audio equipment.
• Gain adjustment in signal conditioning circuits.
• Voltage reference trimming in measurement systems.

Digital Potentiometers Part Context

This component belongs to the X9317 family of digital potentiometers. Variants within this family differ primarily by resistance value (e.g., 10k, 50k, 100k), package type (SOIC, TSSOP, MSOP), and temperature grade. The 'U' suffix typically denotes the SOIC package, while 'S8' indicates the specific pinout and package style for this variant.

Digital Potentiometers Replacement Considerations

Direct replacements include other X9317 variants with matching 50k resistance and non-volatile memory, such as X9317WS8Z-2.7 or X9317UV8IZ-2.7, provided the package footprint (SOIC-8 vs TSSOP-8) is compatible with the PCB design. Verify interface compatibility and voltage ranges before substitution.
