ISL23415WFUZ-TK

Digital Potentiometers Overview

The ISL23415WFUZ-TK is a single-channel digital potentiometer from the Renesas XDCP series, housed in a 10-MSOP surface-mount package. It features a nominal resistance of 10 kOhms with a linear taper and 256 discrete tap positions for precise adjustment. The device utilizes a volatile memory type and communicates via an SPI serial interface. It operates within a supply voltage range of 1.7V to 5.5V and supports an extended industrial temperature range from -40°C to +125°C.

Digital Potentiometers Feature Summary

• Single circuit configuration with 10k Ohm total resistance and 256 taps
• SPI serial interface for digital control
• Linear taper characteristic with ±20% tolerance
• Operates on 1.7V to 5.5V supply voltage

Digital Potentiometers Applications

• Industrial controls requiring adjustable gain or bias
• Calibration circuits for sensor signal conditioning
• Volume or tone control in audio equipment

Digital Potentiometers Procurement Notes

Verify component status as the base model ISL23415WFUZ is listed as obsolete by the manufacturer. Confirm availability through authorized distributors and check for valid RoHS3 compliance documentation before procurement.

Digital Potentiometers Selection Notes

Select this component when a single-channel, 10k Ohm digital potentiometer with SPI control is required. Ensure the design accommodates volatile memory behavior where settings are lost upon power loss. Verify that the 10-MSOP package dimensions fit the PCB layout constraints.

Digital Potentiometers Part Context

This part belongs to the ISL23415 family of digitally controlled potentiometers. It shares core specifications with variants like the ISL23418UFUZ but differs in resistance value and tap count. The 'TK' suffix typically indicates tube packaging, distinct from tape-and-reel options.

Digital Potentiometers Replacement Considerations

The ISL23415WFUZ-T7A is identified as a parameter-equivalent alternative from Renesas Electronics Corporation.
