X9015US8Z

Digital Potentiometers Overview

The X9015US8Z is a volatile digitally controlled potentiometer (XDCP) from the XDCP series, manufactured by Renesas Electronics Corporation. It features a single potentiometer circuit with 32 taps and a resistance value of 50 kOhms. The device operates on a 5 V supply voltage with a maximum operating voltage of 5.5 V and a minimum of 4.5 V. It utilizes a serial 3-wire interface for control and has a linear taper. The component is housed in an 8-SOIC package and functions within a temperature range of 0°C to +70°C.

Digital Potentiometers Feature Summary

• Single-channel digital potentiometer with 32 adjustable taps
• 50 kOhms nominal resistance with ±20% tolerance
• Volatile wiper memory retains position only during power
• Serial 3-wire interface (U/D, INC, CS) for control

Digital Potentiometers Applications

• Audio volume control circuits
• Variable gain amplifier adjustments
• Voltage reference trimming
• Sensor calibration systems

Digital Potentiometers Procurement Notes

The X9015US8Z is classified as End-of-Life (EOL). Manufacturers have announced discontinuation, meaning no new production units are available. Existing stock may be limited or exhausted. Designers should verify current availability through authorized distributors and prepare for immediate component substitution in active designs.

Digital Potentiometers Selection Notes

Select this component only if volatile memory behavior is acceptable, as wiper positions reset upon power loss. Ensure the design accommodates the 50 kOhms resistance and 32-step resolution. Verify that the 8-SOIC surface-mount package fits the PCB layout constraints. Consider the ±300 ppm/°C temperature coefficient for thermal stability requirements.

Digital Potentiometers Part Context

This part belongs to the X9015 family of low-noise, low-power digitally controlled potentiometers. It is functionally similar to non-volatile variants like the X9315 but lacks EEPROM storage. The 'US8' suffix indicates the SOIC-8 package type. It is part of Renesas's legacy Intersil product line acquired under the XDCP brand.
