X9317WV8IT1

Digital Potentiometers Overview

The X9317WV8IT1 is a single-channel digital potentiometer from the XDCP series, manufactured by Renesas Electronics Corporation. It features a total resistance of 10 kOhms with a linear taper and 100 tap positions for precise adjustment. The device utilizes non-volatile memory to retain wiper settings upon power loss. It operates on a 5 V supply voltage with a typical current consumption of 50 uA. The component supports serial control via an Up/Down (U/D), Increment (INC), and Chip Select (CS) interface. It is housed in an 8-TSSOP surface-mount package and is rated for operation within a temperature range of 0°C to +70°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power-off
• 100-tap resolution with linear taper characteristic
• Low power consumption of 50 uA at 5 V supply
• Serial interface compatible with U/D, INC, and CS signals

Digital Potentiometers Applications

• Audio volume control circuits
• Programmable gain amplifier adjustments
• Voltage reference trimming
• System calibration and offset correction

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors as the X9317 series has undergone manufacturer transitions from Intersil to Renesas. Confirm the specific suffix 'IT1' indicates the correct tape-and-reel packaging format. Check for RoHS compliance status as older stock may differ from current manufacturing runs. Ensure the operating temperature range of 0°C to +70°C meets system requirements.

Digital Potentiometers Selection Notes

Select this model when a 10 kOhm resistance value is required. The 100-tap resolution provides finer adjustment granularity compared to 64-tap variants. Verify that the 5 V supply voltage aligns with the system logic levels. The 8-TSSOP package requires appropriate PCB footprint design. Consider the ±20% resistance tolerance if precision matching is critical for the application.

Digital Potentiometers Part Context

The X9317WV8IT1 belongs to the X9317 family of digitally controlled potentiometers. This family offers various resistance values including 1 kOhm, 10 kOhm, and 50 kOhm options. The 'W' suffix typically denotes the 10 kOhm variant, while 'V8I' specifies the TSSOP-8 package and industrial/commercial temperature grades. The 'T1' suffix indicates reel packaging.

Digital Potentiometers Replacement Considerations

Direct replacements include other X9317 variants with different resistance values such as X9317ZV8IT1 (1 kOhm) or X9317UV8IZ (50 kOhm). Cross-reference with Intersil legacy part numbers like ISL81001 series if sourcing from older inventory. Ensure pin compatibility and software interface protocols match when substituting.
