X9015US8Z-2.7

Digital Potentiometers Overview

The X9015US8Z-2.7 is a single digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, formerly Intersil. It features a 50 kOhm end-to-end resistance with a linear taper and 32 tap positions. The device utilizes volatile wiper memory and operates via a serial interface supporting increment/decrement control. It functions within a supply voltage range of 4.5 V to 5.5 V, consuming a maximum operating current of 50 uA. The component is housed in an 8-SOIC surface-mount package and is rated for operation between 0°C and +70°C.

Digital Potentiometers Feature Summary

• Single channel digital potentiometer with 50 kOhm resistance and 32 taps
• Volatile wiper position storage requiring power-on initialization
• Serial 3-wire interface for increment/decrement control
• Operates on a single 5V supply with low 50 uA current consumption

Digital Potentiometers Applications

• Programmable gain amplifiers
• Audio volume control circuits
• Voltage reference adjustment
• Offset voltage trimming

Digital Potentiometers Procurement Notes

This component is designated as End-of-Life (EOL) by the manufacturer. Production has ceased, and availability is limited to existing stock or surplus channels. Verification of authenticity and lot traceability is critical when sourcing from third-party distributors due to the discontinued status.

Digital Potentiometers Selection Notes

Select this part only if volatile memory behavior is acceptable, as wiper positions are lost upon power loss. Ensure the system design includes logic to restore the desired resistance value immediately after power-up. Verify that the 5V supply requirement aligns with the target application's voltage rails.

Digital Potentiometers Part Context

The X9015 series belongs to the XDCP family of digitally controlled potentiometers. This specific model represents the non-volatile EEPROM variant (X9315) or volatile variant (X9015) depending on the suffix interpretation, but datasheets for X9015US8Z indicate volatile memory. The US8Z suffix denotes the SOIC-8 package with lead-free RoHS compliance.
