AD605BR-REEL7

Overview

The AD605BR-REEL7 is a dual, low-noise, single-supply variable gain amplifier manufactured by Analog Devices Inc. It features a 40 MHz gain-bandwidth product and operates on a single supply voltage ranging from 4.5 V to 5.5 V. The device provides a voltage gain of 34 dB with an input bias current of 400 nA and consumes 23 mA of operating current. Packaged in a 16-pin SOIC surface-mount format, it is designed for applications requiring high dynamic range signal processing.

Feature Summary

• Integrates a variable gain amplifier and precision rectifier within a single package
• Provides continuous gain control via logic interface for high dynamic range operation
• Optimized for low noise performance in single-supply environments

Applications

• Medical imaging systems such as ultrasound diagnostics
• Wireless communication infrastructure
• Industrial automation signal conditioning

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as this specific reel variant may be discontinued. Ensure the receiving facility handles ESD-sensitive components appropriately during storage and assembly.

Selection Notes

Select this component when a dual-channel VGA with integrated rectification is required for single-supply designs. Consider the 40 MHz bandwidth and 34 dB gain limits against system requirements. Evaluate the SOIC-16 package constraints for PCB layout and thermal management compared to alternative PDIP or QFN options.

Part Context

This part belongs to the AD605 series of special purpose amplifiers. It shares functional characteristics with variants like the AD605ANZ and AD605BRZ-R7, differing primarily in packaging style and manufacturing lot specifications. The series is categorized under variable gain amplifiers within Analog Devices' portfolio.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative dual-channel VGAs.
