AD5206BRZ10-REEL

Overview

The AD5206BRZ10-REEL is a six-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 ±2.3 V to ±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 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 (suffix 10)
• 3-wire SPI-compatible serial data input interface
• +2.7 V to +5.5 V single-supply or ±2.3 V to ±2.7 V dual-supply operation

Applications

• Mechanical potentiometer replacement
• Instrumentation gain and offset adjustment
• Programmable voltage-to-current conversion
• Programmable filters, delays, and time constants
• Line impedance matching

Procurement Notes

Verify the ordering suffix 'REEL' indicates tape-and-reel packaging rather than tube. Confirm the '10' suffix corresponds to the 10 kΩ resistance variant. Check current manufacturing status as older variants may be obsolete. Ensure ESD precautions are observed during handling due to sensitivity ratings.

Selection Notes

Select this model when six channels are required within a 24-lead footprint. Choose the 10 kΩ version for lower bandwidth applications compared to higher resistance options. Verify that the 700 ppm/°C temperature coefficient meets system drift requirements. Ensure the serial interface timing matches the microcontroller's SPI capabilities.

Part Context

This component belongs to the AD5204/AD5206 family of digital potentiometers. The AD5206 specifically provides six channels, whereas the AD5204 offers four. Both share identical electrical characteristics and pinouts for the first four channels. The BRZ designation typically indicates a specific temperature grade and lead-free RoHS-compliant packaging.

Replacement Considerations

Direct functional substitutes include other 6-channel digital potentiometers from Analog Devices such as the AD840x series, though channel counts differ. Cross-model compatibility exists with the AD5204 for the first four channels if only four are utilized.
