AD5263BRU200

Digital Potentiometers Overview

The AD5263BRU200 is a quad-channel, 256-position digital potentiometer manufactured by Analog Devices Inc. It features an end-to-end resistance of 200 kΩ with a nominal temperature coefficient of ±30 ppm/°C and a wiper resistance of 60 Ω. The device supports pin-selectable SPI or I²C interfaces 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. It includes power-on preset to midscale, two address decode pins for bus expansion, and a self-contained shutdown function. The component is housed in a 24-lead TSSOP package and is rated for operation between –40°C and +125°C.

Digital Potentiometers Feature Summary

• Quad-channel architecture with 256 programmable positions per channel
• Pin-selectable SPI (DIS=0) or I²C (DIS=1) digital interface
• End-to-end resistance options including 200 kΩ with ±30% tolerance
• Power-on preset to midscale position for fault recovery

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 specific resistance value suffix (e.g., 200 for 200 kΩ) against design requirements. Confirm the package type is 24-TSSOP. Check for RoHS compliance status as manufacturing sites may vary. Ensure logic supply voltage (VL) does not exceed VDD or 5.5 V during system integration.

Digital Potentiometers Selection Notes

Select this component when four independent variable resistors are required on a single chip. The 200 kΩ variant suits high-impedance applications. Consider the 30 ppm/°C rheostat temperature coefficient for precision needs. Verify that the volatile memory type aligns with the application's power-loss behavior requirements.

Digital Potentiometers Part Context

The AD5263 series represents the industry’s first quad-channel digital potentiometer with a selectable interface. It serves as a solid-state alternative to mechanical pots, offering enhanced reliability and low temperature coefficient performance. Related parts include the AD5260 (single channel) and AD5262 (dual channel).

Digital Potentiometers Replacement Considerations

The AD5263BRUZ200 is a direct replacement for the discontinued AD5263BRU200. Both share identical electrical specifications and pinouts. Verify that the 'Z' suffix indicates the same 24-TSSOP narrow body package.
