AD5206BRUZ100-RL7

Overview

The AD5206BRUZ100-RL7 is a six-channel, 8-bit digital potentiometer from Analog Devices. It provides 256 programmable tap positions with a nominal terminal resistance of 100 kΩ and a linear taper. The device operates on a single supply voltage ranging from +2.7 V to +5.5 V or dual supplies up to ±2.7 V. It features volatile memory and communicates via a standard 3-wire SPI-compatible serial interface. Each channel includes independent latches for resistance control, allowing random access updates. The component is housed in a 24-lead TSSOP package and is rated for operation within the extended industrial temperature range of −40°C to +85°C.

Feature Summary

• Six independently programmable channels with 256-position resolution
• Nominal end-to-end resistance of 100 kΩ with linear taper
• SPI-compatible 3-wire serial interface (CS, CLK, SDI)
• Power-on midscale preset capability via internal circuitry

Applications

• Mechanical potentiometer replacement
• Instrumentation gain and offset adjustment
• Programmable filters, delays, and time constants
• Line impedance matching

Procurement Notes

Verify the ordering suffix RL7 confirms tape-and-reel packaging when sourcing. Confirm the BRUZ designation corresponds to the specific temperature grade and TSSOP package variant required for the design. Cross-reference the final part number against the manufacturer's current datasheet revision to ensure parameter consistency.

Selection Notes

Select this model for applications requiring six isolated variable resistors with 100 kΩ nominal values. Ensure the system logic levels are compatible with the specified input thresholds at the chosen supply voltage. Consider the 700 ppm/°C temperature coefficient if precise absolute resistance stability over wide thermal ranges is critical.

Part Context

This component 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, serial interfaces, and pinout architectures, differing primarily in channel count and physical pin assignments for the additional terminals.

Replacement Considerations

Direct functional replacements include other 6-channel digital potentiometers with SPI interfaces and similar resistance values. Verify that substitute components match the 24-lead TSSOP footprint and support the required voltage range. Check if the alternative device offers nonvolatile memory if power-loss retention is necessary.
