AD5206BRUZ100

Overview

The AD5206BRUZ100 is a six-channel, 256-position digitally controlled variable resistor from Analog Devices. It operates on a single +2.7 V to +5.5 V supply or ±2.7 V dual supply. The device features a 100 kΩ nominal terminal resistance with a 700 ppm/°C temperature coefficient. Control is managed via a 3-wire SPI-compatible serial interface using an 11-bit data word. Each channel includes an independent latch for resistance storage and supports power-on midscale preset functionality.

Feature Summary

• Six independently programmable channels with 256 positions
• 100 kΩ fixed A-to-B terminal resistance
• 3-wire SPI-compatible serial interface (CS, CLK, SDI)
• +2.7 V to +5.5 V single-supply or ±2.7 V dual-supply operation

Applications

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

Procurement Notes

Verify the ordering suffix '100' confirms the 100 kΩ resistance value. Confirm the 'RUZ' suffix corresponds to the 24-lead TSSOP package. Ensure compatibility with the required supply voltage range of +2.7 V to +5.5 V. Check for updated revision status against the latest Analog Devices documentation.

Selection Notes

Select this model for applications requiring six independent digital potentiometer channels. The 100 kΩ resistance value suits moderate impedance circuits. The TSSOP package is suitable for surface-mount assembly. Verify that the 3-wire SPI interface aligns with the host controller's available pins.

Part Context

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

Replacement Considerations

Direct substitutes include other AD5206 variants with different resistance values (e.g., AD5206BRUZ10) or packages. Cross-family replacements like the AD840x series offer similar functionality but may differ in channel count or interface requirements.
