AD5207BRU100-REEL7

Overview

The AD5207BRU100-REEL7 is a dual-channel, 8-bit digital potentiometer IC manufactured by Analog Devices. It features two independent potentiometers with linear taper and 256 tap positions per channel. The nominal resistance value is 100 kOhms with a tolerance of 30% and a temperature coefficient of 500 PPM/C. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, drawing a typical operating current of 20 nA. It utilizes an SPI-compatible serial interface for control and employs volatile brush memory to retain wiper settings during operation.

Feature Summary

• Dual-channel architecture with 256 discrete tap positions per potentiometer
• 100 kOhms nominal resistance with linear taper characteristic
• SPI-compatible 3-wire serial control interface
• Wide operating voltage range from 2.7 V to 5.5 V

Applications

• Programmable gain amplifier circuits
• Digital volume control in audio systems
• Variable reference voltage generation
• Sensor bias adjustment

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm resistance tolerance and package variations. Confirm RoHS compliance status through the manufacturer's latest datasheet or component certification records before integration into regulated assemblies.

Selection Notes

Select this component when dual-channel programmable resistance is required within a 100 kOhms range. Ensure the system design accommodates the 30% resistance tolerance and 500 PPM/C temperature coefficient. Verify that the application supports volatile memory behavior, as wiper positions are lost upon power removal.

Part Context

This part belongs to the AD5207 series of digital potentiometers. It shares the same core architecture and interface protocols with other variants in the family, differing primarily in resistance values (e.g., 50 kOhms) and packaging options. The BRU designation indicates a specific industrial temperature grade and TSSOP-14 package configuration.

Replacement Considerations

Cross-reference with AD5207BRUZ100-R7 for identical electrical specifications and pinout compatibility. Verify package dimensions and marking codes to ensure mechanical fit in existing PCB layouts.
