Digital Potentiometers datasheet and documents for ISL23448TFRZ-T7A

ISL23448TFRZ-T7A

Digital Potentiometers Overview

The ISL23448TFRZ-T7A is a volatile, low voltage, low noise, and low power quad digitally controlled potentiometer (DCP) featuring an SPI Bus interface. It integrates four independent DCP cores, each with 128 taps, along with wiper switches and control logic on a monolithic CMOS integrated circuit. The device operates within a temperature range of -40°C to +125°C and is available in QFN20 and TSSOP20 packages.

Digital Potentiometers Feature Summary

Quad architecture with four independent 128-tap digitally controlled potentiometers
SPI Bus interface for digital control
Integrated wiper switches and control logic
Low voltage operation with low noise and low power consumption

Digital Potentiometers Part Context

This component belongs to the ISL234xx series of XDCP devices from Intersil (now Renesas). The datasheet indicates that the ISL23448 is not recommended for new designs, suggesting it may be superseded by newer iterations within the family or subject to discontinuation notices common to legacy Intersil products.

Digital Potentiometers Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers should consult current Renesas catalogs for updated quad DCP alternatives, as the ISL23448 is explicitly marked as not recommended for new designs.
