AD5260BRUZ20-RL7

Digital Potentiometers Overview

The AD5260BRUZ20-RL7 is a single-channel, 8-bit digital potentiometer from Analog Devices. It provides 256 programmable tap positions with a nominal resistance of 20 kΩ and a tolerance of ±30%. The device operates on a single supply (4.5 V to 16.5 V) or dual supplies (±4.5 V to ±5.5 V). It features an SPI-compatible serial interface for data input and output. Key electrical parameters include a temperature coefficient of 35 ppm/°C, wiper resistance of 60 Ω typical, and shutdown current of 5 μA. The unit is housed in a 14-lead TSSOP package.

Digital Potentiometers Feature Summary

• Single-channel variable resistor with 256 linear tap positions
• SPI-compatible 4-wire serial interface with daisy-chain capability via SDO pin
• Operates on single-supply (up to 16.5 V) or dual-supply (±5.5 V)
• Power-on midscale preset and active-low PR pin for immediate centering

Digital Potentiometers Applications

• Mechanical potentiometer replacement in instrumentation
• Programmable gain and offset adjustment circuits
• Stereo channel audio level control
• Programmable voltage-to-current conversion
• Line impedance matching

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the required reel packaging quantity when sourcing. Confirm that the BRUZ variant matches the necessary industrial temperature range (-40°C to +85°C) and lead-free compliance requirements for the target assembly process.

Digital Potentiometers Selection Notes

Select this component for applications requiring a single digitally controlled resistor with high voltage tolerance up to 15 V. Ensure the logic supply voltage (VL) aligns with the controlling microcontroller's I/O levels. For multi-device systems, utilize the SDO pin for daisy-chaining to reduce pin count compared to independent chip select lines.

Digital Potentiometers Part Context

This part belongs to the AD5260/AD5262 family of 15 V digital potentiometers. The AD5260 variant specifically integrates one channel, whereas the AD5262 offers two independently programmable channels within a 16-lead package. Both share identical core specifications regarding resolution, interface, and power characteristics.
