AD5206BRUZ50-REEL7

Overview

The AD5206BRUZ50-REEL7 is a six-channel, 256-position digitally controlled variable resistor from Analog Devices. It features a 3-wire SPI-compatible serial interface for independent channel programming. The device operates on a single supply of +2.7 V to +5.5 V or dual supplies of ±2.7 V. It includes a power-on midscale preset and supports daisy-chaining via an SDO pin. The nominal terminal resistance is 50 kΩ with a temperature coefficient of 700 ppm/°C. It 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
• 3-wire SPI-compatible serial interface with daisy-chain capability
• Power-on midscale preset and hardware reset functionality
• Operates on +2.7 V to +5.5 V single supply or ±2.7 V dual supply

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 ordering suffix REEL7 indicates tape-and-reel packaging. Confirm the BRZ suffix corresponds to the industrial temperature grade and lead-free RoHS compliance. Ensure the UZ suffix matches the required 24-lead TSSOP package type. Cross-reference the specific revision level against current Analog Devices documentation to ensure data sheet accuracy.

Selection Notes

Select this component when six independent digital potentiometer channels are required within a single package. The 50 kΩ terminal resistance suits moderate impedance applications. Verify that the 256-position resolution meets system precision requirements. Ensure the host controller supports the 3-wire SPI protocol and can handle the necessary clock speeds for data setup and hold times.

Part Context

This part belongs to the AD5204/AD5206 family of 4-/6-channel digital potentiometers. The AD5206 variant specifically provides six channels compared to the four channels in the AD5204. Both share identical electrical characteristics, interface protocols, and package options, differing primarily in channel count and address decoding logic for the additional channels.

Replacement Considerations

Direct functional equivalents include other 6-channel digital potentiometers from Analog Devices such as the AD5206 series variants with different resistance values or packages. Verify pin compatibility and serial interface timing requirements before substitution.
