AD5262BRU200

Digital Potentiometers Overview

The AD5262BRU200 is a dual-channel, 8-bit digital potentiometer from Analog Devices. It provides two independently programmable variable resistors with 256 tap positions and a nominal resistance of 200 kΩ. The device features a linear taper and operates on a single supply of 4.5 V to 16.5 V or a dual supply of ±4.5 V to ±5.5 V. It utilizes a 4-wire SPI-compatible serial interface for data input and includes an SDO pin for daisy-chaining. Key electrical characteristics include a temperature coefficient of 35 ppm/°C, wiper resistance of 60 Ω typical, and a shutdown current of 5 μA. The part is housed in a 16-lead TSSOP package.

Digital Potentiometers Feature Summary

• Dual-channel architecture with independent 8-bit control for each channel
• 200 kΩ nominal resistance with 256 programmable tap positions
• SPI-compatible 4-wire serial interface with daisy-chain capability via SDO
• Power-on midscale preset and active-low PR pin for immediate centering

Digital Potentiometers Applications

• Mechanical potentiometer replacement in industrial systems
• Instrumentation gain and offset adjustment circuits
• Stereo channel audio level control
• Programmable voltage-to-current conversion
• Low resolution DAC replacement

Digital Potentiometers Procurement Notes

Verify the specific suffix against the manufacturer's ordering guide to confirm package type and tape/reel specifications. Confirm RoHS compliance status as it may vary by production lot. Check for obsolescence notices or PCNs regarding wafer fab site changes before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this component when dual-channel digital resistance control is required within a 15 V maximum supply range. Ensure the system logic voltage matches the VL pin requirement (2.7 V to 5.5 V). Verify that the 200 kΩ resistance value aligns with the target bandwidth and current handling requirements, noting the -3 dB bandwidth is approximately 30 kHz at this resistance.

Digital Potentiometers Part Context

This part belongs to the AD5260/AD5262 family of 15 V digital potentiometers. The AD5262 specifically denotes the dual-channel variant, whereas the AD5260 is single-channel. Both share identical electrical specifications and pinouts for their respective channels, differing only in the number of RDAC latches and address bits required for the serial interface.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include the AD5262BRU50 (50 kΩ) and AD5262BRUZ20 (20 kΩ). For single-channel applications, the AD5260 series serves as a functional subset. Cross-vendor equivalents require verification of SPI compatibility, voltage ratings, and resistance tolerance.
