AD5206BRU10-REEL7

Overview

The AD5206BRU10-REEL7 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 unit utilizes a 24-lead TSSOP surface-mount package and guarantees operation across the 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 wiper movement
• 3-wire SPI-compatible serial interface for digital control
• Power-on midscale preset for safe initialization

Applications

• Mechanical potentiometer replacement in embedded systems
• Instrumentation gain and offset adjustment
• Programmable voltage-to-current conversion circuits
• Line impedance matching applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm package type and tape-and-reel specifications. Confirm that the 10 kΩ resistance variant matches the circuit requirements. Ensure ESD handling protocols are followed during assembly due to the sensitivity of the CMOS input structures.

Selection Notes

Select this component when a multi-channel solution is required to replace mechanical pots in space-constrained designs. The 10 kΩ value offers a balance between power consumption and noise performance. Consider the 256-position resolution for applications requiring moderate precision without the complexity of a DAC. Verify that the serial interface timing meets the microcontroller's clock speed capabilities.

Part Context

This part belongs to the AD5204/AD5206 family of digital potentiometers. While the AD5204 provides four channels, the AD5206 extends this to six channels within the same pinout footprint. Both share identical electrical characteristics and control logic, allowing for design flexibility in scaling channel counts without changing the core interface architecture.

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-compatibility requires verifying the serial protocol compatibility and ensuring the replacement package matches the 24-lead TSSOP dimensions.
