AD5206BRZ10

Overview

The AD5206BRZ10 is a 6-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 ±2.7 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 surface-mount package and supports an extended 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
• Line impedance matching

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and resistance value. Confirm availability status as older revisions may be discontinued. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS inputs.

Selection Notes

Select this component when six independent digital potentiometer channels are required within a single package. The 10 kΩ resistance value suits applications requiring moderate current handling compared to higher resistance variants. Verify that the system logic levels are compatible with the 3-wire SPI interface requirements.

Part Context

This component belongs to the AD5204/AD5206 family of digital potentiometers. The AD5206 variant specifically provides six channels, whereas the AD5204 offers four. Both share identical electrical characteristics, interface protocols, and package options, 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 and interfaces may vary. Cross-vendor replacements require verification of pin compatibility and serial protocol support.
