ISL23511WFB8Z

Digital Potentiometers Overview

The ISL23511WFB8Z is a single-channel digital potentiometer IC manufactured by Renesas Electronics. It features a total resistance of 10 kOhms with a linear taper and 32 tap positions for wiper adjustment. The device operates on a supply voltage range of 2.7 V to 5.5 V, consuming a typical operating current of 150 uA. It utilizes a push-button interface for control and employs volatile memory to retain wiper settings during power cycles. The component is housed in an 8-lead SOIC package and supports surface mount installation.

Digital Potentiometers Feature Summary

• Single channel digital potentiometer with 10 kOhms resistance and 32 taps
• Push-button interface for manual wiper position adjustment
• Volatile storage mechanism for wiper position data
• Operates within 2.7 V to 5.5 V supply voltage range

Digital Potentiometers Applications

• Manual gain or offset adjustment in instrumentation circuits
• Volume control or bias setting in audio equipment
• Voltage reference trimming in power supply designs
• Calibration adjustments in industrial sensor interfaces

Digital Potentiometers Procurement Notes

Verify the specific suffix 'WFB8Z' against the manufacturer's official datasheet to confirm pinout compatibility and tape-and-reel specifications. Ensure that the volatile memory characteristic aligns with system requirements, as wiper positions will reset upon power loss. Confirm RoHS compliance status through the latest Renesas documentation before finalizing procurement orders.

Digital Potentiometers Selection Notes

Select this component when a simple, low-pin-count solution for manual resistance adjustment is required without serial communication overhead. The push-button interface suits applications where direct user interaction is necessary. Consider the 20% tolerance and 80 PPM/C temperature coefficient if precise stability across wide temperature ranges is critical for the application design.

Digital Potentiometers Part Context

This part belongs to the ISL23511 series of digital potentiometers from Renesas (formerly Intersil). The series offers various resistance values and interface options. The WFB8Z designation specifically indicates the 10 kOhm variant in an 8-lead SOIC package, distinguishing it from other series members with different resistances or packaging styles.

Digital Potentiometers Replacement Considerations

Check for cross-reference parts within the ISL23511 family that may offer non-volatile memory if power retention is needed. Verify pin-to-pin compatibility with alternative digital potentiometers from other manufacturers, ensuring interface signals match the push-button control scheme.
