AD5260BRUZ200-RL7

Digital Potentiometers Overview

The AD5260BRUZ200-RL7 is a single-channel, 8-bit digital potentiometer from Analog Devices. It features a nominal resistance of 200 kΩ with a temperature coefficient of 35 ppm/°C and 256 tap positions. The device operates on a single supply of 4.5 V to 16.5 V or dual supplies of ±4.5 V to ±5.5 V, with a logic supply (VL) range of 2.7 V to 5.5 V. It utilizes a 4-wire SPI-compatible serial interface for data input and output. Packaged in a 14-lead TSSOP, it includes power-on midscale preset functionality and an active-low shutdown pin.

Digital Potentiometers Feature Summary

• Single-channel variable resistor with 200 kΩ nominal resistance and 256 programmable positions
• Operates on single-supply voltages up to 16.5 V or dual supplies up to ±5.5 V
• SPI-compatible 4-wire serial interface with daisy-chain capability via SDO pin
• Power-on reset forces wiper to midscale position; optional PR pin for manual mid-scale preset

Digital Potentiometers Applications

• Mechanical potentiometer replacement in industrial equipment
• Instrumentation gain and offset adjustment circuits
• Programmable voltage-to-current conversion systems
• Line impedance matching applications

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging configuration required for assembly. Confirm that the BRUZ variant matches the thermal and mechanical specifications needed for the target PCB footprint. Ensure the logic supply voltage aligns with the controlling microcontroller's I/O levels before integration.

Digital Potentiometers Selection Notes

Select this component when a single-channel digital control is sufficient, as opposed to the dual-channel AD5262. The 200 kΩ resistance value suits high-impedance signal paths. Verify that the system can accommodate the 256-position resolution and that the 35 ppm/°C temperature coefficient meets the stability requirements of the application environment.

Digital Potentiometers Part Context

This part belongs to the AD5260/AD5262 family of 15 V digital potentiometers. It shares the same core architecture and interface protocols as the AD5262 but provides only one variable resistor channel. It serves as a direct electronic replacement for traditional mechanical potentiometers in space-constrained surface-mount designs.
