X9317WM8IT1

Digital Potentiometers Overview

The Intersil X9317WM8IT1 is a digitally controlled potentiometer (XDCP) featuring a single resistive element with 100 tap positions. It utilizes an increment/decrement control interface for wiper adjustment and includes nonvolatile memory to retain the setting upon power loss. The device operates within a supply voltage range of 4.5 V to 5.5 V, consuming a typical operating current of 50 µA. It is housed in an MSOP-8 surface-mount package and supports an industrial temperature range from -40 °C to +85 °C.

Digital Potentiometers Feature Summary

• Single-channel digital potentiometer with 100 linear tap positions
• Nonvolatile memory retains wiper position after power cycle
• Low power consumption with 50 µA typical operating current
• Increment/Decrement control interface via CS, U/D, and INC pins

Digital Potentiometers Applications

• Audio volume control circuits
• Programmable gain amplifier biasing
• Voltage reference trimming
• LCD contrast adjustment

Digital Potentiometers Procurement Notes

Verify the specific suffix 'IT1' against the manufacturer's official datasheet FN8183 to confirm tape-and-reel packaging and extended temperature ratings. Ensure compatibility with existing PCB footprints for the MSOP-8 package. Cross-reference RoHS compliance status as manufacturing sites may vary.

Digital Potentiometers Selection Notes

Select this component when a single-channel, nonvolatile digital potentiometer with 100 taps is required. The 10 kΩ resistance value suits moderate impedance applications. Verify that the 3-wire increment/decrement interface aligns with the system controller's GPIO capabilities. Consider the ±20% tolerance and ±300 ppm/°C temperature coefficient for precision requirements.

Digital Potentiometers Part Context

The X9317 belongs to the XDCP family of low-noise, low-power digitally controlled potentiometers. This series integrates resistor arrays, wiper switches, and EEPROM into a compact package. The WM8 designation indicates the 10 kΩ resistance value and MSOP-8 packaging variant within the broader X9317 product line.

Digital Potentiometers Replacement Considerations

Direct pin-compatible alternatives include other X9317 variants with different resistance values or packages, such as X9317ZM8I or X9317WS8IZ. Verify interface compatibility and memory retention features when substituting.
