AD5206BR10

Overview

The AD5206BR10 is a six-channel, 256-position digitally controlled variable resistor from Analog Devices. It operates on a single +2.7 V to +5.5 V supply or ±2.7 V dual supply. The device features a 3-wire SPI-compatible serial interface for programming resistance values between terminals A and B. Each channel provides independent control with a nominal terminal resistance of 10 kΩ and a temperature coefficient of 700 ppm/°C. The unit includes power-on midscale preset functionality and operates within an industrial temperature range of −40°C to +85°C.

Feature Summary

• Six independently programmable channels with 256 positions
• 10 kΩ nominal terminal resistance with 700 ppm/°C temperature coefficient
• 3-wire SPI-compatible serial data input interface
• +2.7 V to +5.5 V single-supply or ±2.7 V dual-supply operation

Applications

• Mechanical potentiometer replacement
• Instrumentation gain and offset adjustment
• Programmable voltage-to-current conversion
• Programmable filters, delays, and time constants
• Line impedance matching

Procurement Notes

Verify the specific package type required for the AD5206BR10 variant against the manufacturer's ordering guide. Confirm that the selected component meets the necessary thermal and electrical specifications for the intended application environment. Ensure proper handling procedures are followed due to electrostatic discharge sensitivity.

Selection Notes

Select the AD5206BR10 when six independent digital potentiometer channels are required in a compact form factor. Choose this model over the AD5204 if additional channels are needed without increasing the number of integrated circuits. Consider the 10 kΩ resistance value and SPI interface compatibility with the host microcontroller before finalizing the design.

Part Context

The AD5206BR10 belongs to the AD5204/AD5206 family of 4- and 6-channel digital potentiometers. This series serves as electronic replacements for mechanical potentiometers, offering precise, digitally adjustable resistance values. The BR suffix typically indicates a specific package configuration, such as TSSOP or SOIC, available in 24-lead surface-mount options.

Replacement Considerations

Direct substitutes include other models within the AD5204/AD5206 family, such as the AD5206BRZ50 (50 kΩ) or AD5206BRZ100 (100 kΩ), provided the resistance value matches the circuit requirements. Ensure pin compatibility and interface standards align when replacing components.
