AD5206BRUZ10-RL7

Overview

The AD5206BRUZ10-RL7 is a six-channel, 256-position digitally controlled variable resistor from Analog Devices. It features a 10 kΩ nominal terminal resistance with a 700 ppm/°C temperature coefficient. The device operates on a single supply of +2.7 V to +5.5 V or dual supplies of ±2.3 V to ±2.7 V. It utilizes a 3-wire SPI-compatible serial interface for programming. Each channel includes an independent latch holding the resistance value. The part is housed in a 24-lead TSSOP package and functions over an industrial temperature range of −40°C to +85°C.

Feature Summary

• Six independently programmable channels with 256 positions each
• 10 kΩ nominal end-to-end resistance with linear taper
• 3-wire SPI-compatible serial data input interface
• Power-on midscale preset capability

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 ordering suffix RL7 against the manufacturer's current documentation to confirm reel packaging specifications. Confirm that the BRZ designation aligns with the required commercial grade temperature range and lead-free status as defined in the latest Analog Devices ordering guide.

Selection Notes

Select this component when six independent digital potentiometer channels are required within a compact surface-mount footprint. The 10 kΩ resistance value suits applications requiring moderate current handling compared to higher resistance variants. Ensure the system interface supports the 3-wire SPI protocol and that the 2.7 V to 5.5 V supply range matches the target power architecture.

Part Context

This part belongs to the AD5204/AD5206 family of 4- and 6-channel digital potentiometers. While the AD5204 offers four channels, the AD5206 provides six channels using the same core technology and interface. Both share identical electrical characteristics regarding resolution, linearity, and power consumption, differing primarily in channel count and pinout configuration.

Replacement Considerations

Direct functional substitutes include other 6-channel digital potentiometers from Analog Devices such as the AD840x series, though channel counts may vary. Cross-vendor replacements require verification of SPI compatibility, wiper resistance limits, and package dimensions to ensure board-level interchangeability.
