X9015US8I-2.7

Digital Potentiometers Overview

The Renesas X9015US8I-2.7 is a single digitally controlled potentiometer (XDCP) featuring 32 taps and volatile memory. It operates within a supply voltage range of 2.7V to 5V, with a maximum operating current of 50µA and standby current of 1µA. The device utilizes a 3-wire serial interface for increment/decrement control. Available in an 8-SOIC package, it offers resistance values of 10kΩ, 50kΩ, or 100kΩ with linear taper. The industrial temperature grade (-40°C to +85°C) supports applications requiring precise analog value setting via digital signals.

Digital Potentiometers Feature Summary

• 32-tap resolution with volatile wiper position storage
• 3-wire up/down serial interface for tap adjustment
• Low power consumption: 50µA operating, 1µA standby
• Supply voltage range: 2.7V to 5V

Digital Potentiometers Applications

• Digitally variable resistors for setting analog values
• Gain control in signal conditioning circuits
• Bias voltage adjustment in sensor interfaces

Digital Potentiometers Procurement Notes

Verify component status as the X9015 series has been subject to End-of-Life notices by Renesas. Confirm availability through authorized distributors or secondary market sources. Ensure RoHS compliance matches specific project requirements, noting that Pb-free plus anneal variants are available. Check for potential obsolescence risks before finalizing design-in decisions.

Digital Potentiometers Selection Notes

Select this variant for its extended industrial temperature range (-40°C to +85°C) compared to commercial grades. Choose based on required total resistance (10kΩ, 50kΩ, or 100kΩ) and package type (SOIC-8). Note that the wiper position resets to Tap #15 upon power-up due to volatile memory; external circuitry may be needed to restore settings if retention across power cycles is required.

Digital Potentiometers Part Context

The X9015US8I-2.7 belongs to the X9015 family of low-noise, low-power volatile digital potentiometers originally developed by Intersil and later acquired by Renesas. It serves as a direct replacement for legacy analog potentiometers in space-constrained PCB designs where manual adjustment is unnecessary.

Digital Potentiometers Replacement Considerations

Direct pin-compatible alternatives include the X9015US8Z (commercial grade) or X9015UM8IZT1 (MSOP-8 package). For non-volatile data retention, consider the X9315 series. Verify that substitute components match the specific resistance tolerance and temperature coefficient requirements.
