AD5263BRUZ20-REEL7

Digital Potentiometers Overview

The AD5263BRUZ20-REEL7 is a quad-channel, 8-bit digital potentiometer with 256 tap positions and a nominal end-to-end resistance of 20 kΩ. It features a pin-selectable SPI or I²C interface and operates from a single supply of +4.5 V to +16.5 V or dual supplies of ±4.5 V to ±7.5 V. The device includes programmable logic outputs (O1, O2) in I²C mode, power-on preset to midscale, and a shutdown function. It is housed in a 24-lead TSSOP package and supports an operating temperature range of –40°C to +125°C.

Digital Potentiometers Feature Summary

• Quad-channel architecture with 256-position resolution per channel
• Pin-selectable SPI or I²C-compatible serial interface
• Programmable logic outputs (O1, O2) for driving external loads in I²C mode
• Power-on wiper preset to midscale position

Digital Potentiometers Applications

• Mechanical potentiometer replacement
• Instrumentation gain and offset adjustment
• Stereo channel audio level control
• Programmable filters and time constants
• Sensor calibration

Digital Potentiometers Procurement Notes

Verify the ordering suffix REEL7 corresponds to tape-and-reel packaging when sourcing. Confirm the '20' designation indicates the 20 kΩ resistance variant. Ensure the DIS pin configuration matches the required bus protocol (SPI or I²C) for the target application design.

Digital Potentiometers Selection Notes

Select this component for applications requiring four independent variable resistors controlled via standard serial buses. The 20 kΩ value suits moderate impedance circuits. Consider the 30% tolerance and 30 ppm/°C temperature coefficient for precision requirements. Dual-supply operation allows bipolar signal handling.
