X9317TV8IZ

Digital Potentiometers Overview

The X9317TV8IZ is a single-channel Digital Controlled Potentiometer (XDCP) manufactured by Intersil. It features a total resistance of 100 kOhms with 100 discrete taps for precise adjustment. The device utilizes non-volatile memory to retain the wiper position upon power loss. It operates on a supply voltage range of 2.7 V to 5.5 V and draws a typical operating current of 50 uA. The component supports an industrial temperature range from -40 °C to +85 °C and employs a linear taper profile.

Digital Potentiometers Feature Summary

• 100 kOhms total resistance with 100 tap positions
• Non-volatile memory retains wiper setting after power cycle
• Serial 3-Wire digital interface for control
• Operating voltage range: 2.7 V to 5.5 V

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Digital volume control in audio circuits

Digital Potentiometers Procurement Notes

Verify the specific suffix 'V8IZ' against the manufacturer's latest datasheet to confirm pinout compatibility and package type, as variations exist within the X9317 family. Confirm that the 2.7 V minimum supply voltage aligns with the target system design requirements before integration.

Digital Potentiometers Selection Notes

Select this component when a high-resistance value (100 kOhms) is required compared to other variants like the 10 kOhm or 50 kOhm versions. Ensure the application requires a linear taper rather than logarithmic. Verify that the serial interface protocol matches the microcontroller's available communication lines.

Digital Potentiometers Part Context

This part belongs to the X9317 series of CMOS digitally controlled potentiometers. It shares architectural similarities with other members such as the X9317UV8IZ and X9317ZV8IZ, differing primarily in resistance value and specific package options. The series is characterized by its non-volatile storage capability and low power consumption.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9317 variants with matching resistance if the circuit allows, such as X9317UV8IZ (50 kOhms) or X9317WM8IZ (10 kOhms), provided the interface and voltage specs are compatible.
