AD5206BRU10

Overview

The AD5206BRU10 is a six-channel, 256-position digitally controlled variable resistor from Analog Devices. It features a nominal terminal resistance of 10 kΩ with a temperature coefficient of 700 ppm/°C. 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. Each channel includes an independent latch updated via a 3-wire SPI-compatible serial interface. The part is housed in a 24-lead TSSOP package and guarantees operation over the 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 wiper movement
• 3-wire SPI-compatible serial interface for data input
• Power-on midscale preset for safe initialization

Applications

• Mechanical potentiometer replacement
• Instrumentation gain and offset adjustment
• Programmable voltage-to-current conversion
• Line impedance matching

Procurement Notes

Verify the specific ordering suffix RU10 against the manufacturer's current ordering guide to confirm the package type and tape-and-reel specifications. Confirm that the 10 kΩ resistance variant matches the system requirements, as other values like 50 kΩ and 100 kΩ are available in the same family.

Selection Notes

Select this component when six independent digital potentiometer channels are required in a compact surface-mount package. Ensure the system logic levels are compatible with the 3-wire SPI interface and that the 10 kΩ resistance value fits the target circuit's power and bandwidth constraints.

Part Context

This part belongs to the AD5204/AD5206 family of 4- and 6-channel digital potentiometers. The AD5206 specifically provides six channels, whereas the AD5204 offers four. Both share identical electrical characteristics, control interfaces, and package options, differing primarily in channel count and pinout configuration.

Replacement Considerations

Direct functional replacements within the same family include the AD5206BU10 (SOIC package) or AD5206BRZ10 (TSSOP package). Verify that any substitute maintains the 24-lead TSSOP footprint and 10 kΩ resistance value.
