X9315USIZT1

Digital Potentiometers Overview

The X9315USIZT1 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics. It features a single potentiometer with a resistance of 50 kOhms and 32 taps. The device utilizes a non-volatile memory to store wiper positions, which are recalled upon power-up. It operates on a 5 V supply with a current consumption of 50 uA. The component uses a 3-wire serial interface for control and is housed in an 8-SOIC package.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position settings across power cycles
• 3-wire serial interface controls the wiper via CS, U/D, and INC inputs
• Linear taper with 32 accessible tap points
• Low power consumption of 50 uA at 5 V operation

Digital Potentiometers Applications

• Audio volume control systems
• Gain adjustment circuits
• Voltage reference trimming

Digital Potentiometers Procurement Notes

The X9315USIZT1 is listed as obsolete or having limited availability from major distributors such as Mouser. Verification of current stock status and alternative sourcing channels is required before procurement planning. Check official Renesas documentation for end-of-life notifications.

Digital Potentiometers Selection Notes

Select this component when a non-volatile digital potentiometer with 50 kOhm resistance and 32 taps is required. Ensure the application supports the 3-wire serial interface and operates within the specified voltage range. Verify that the SOIC-8 package fits the PCB layout constraints.

Digital Potentiometers Part Context

This part belongs to the X9315 series of low noise, low power digitally controlled potentiometers. It is part of the XDCP family, designed for applications requiring precise resistance adjustment without mechanical wear. The 'IZ' suffix typically denotes the industrial temperature range and specific packaging.

Digital Potentiometers Replacement Considerations

Verify compatibility with existing designs if substituting. Other variants in the X9315 family may offer different resistance values or packages. Consult the manufacturer's cross-reference guide for direct replacements.
