AD5206BRU50-REEL7

Overview

The AD5206BRU50-REEL7 is a six-channel, 256-position digitally controlled variable resistor from Analog Devices. It operates on a single supply of +2.7 V to +5.5 V or dual supplies of ±2.7 V. The device features a 3-wire SPI-compatible serial interface for programming resistance values between terminals A and B. Each channel provides independent control with a nominal terminal resistance of 50 kΩ and a temperature coefficient of 700 ppm/°C. The unit utilizes volatile memory, requiring power-on midscale presets.

Feature Summary

• Six independently programmable channels with 256 positions
• 50 kΩ nominal terminal resistance with 700 ppm/°C temperature coefficient
• 3-wire SPI-compatible serial data input (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
• Programmable filters, delays, and time constants
• Line impedance matching

Procurement Notes

Verify the ordering suffix REEL7 indicates tape-and-reel packaging. Confirm the BRU designation corresponds to the 24-lead TSSOP package. Ensure the '50' suffix matches the required 50 kΩ resistance value. Check for RoHS compliance status in the specific manufacturing lot documentation.

Selection Notes

Select this component when six independent digital potentiometer channels are required. The 50 kΩ resistance value suits moderate current applications. Verify that the 256-position resolution meets system accuracy requirements. Ensure the host controller supports the 3-wire SPI protocol for serial data interfacing.

Part Context

This part 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 interfaces, and package options within the same product line.
