AD5206BRUZ10

Overview

The AD5206BRUZ10 is a 6-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 ±2.7 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 700 ppm/°C temperature coefficient
• 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 documentation to confirm package type and resistance tolerance. Confirm availability status as component lifecycles may change. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS inputs and internal switch structures.

Selection Notes

Select this model when six independent digital control channels are required within a single package. The 10 kΩ resistance value offers a balance between power consumption and noise performance. Verify that the system voltage falls within the 2.7 V to 5.5 V single-supply range. Consider the 24-lead TSSOP footprint for PCB layout constraints.

Part Context

This component 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, serial 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-model compatibility requires verification of pin assignments and serial protocol alignment.
