AD605AR-REEL7

Overview

The AD605AR-REEL7 is a dual-channel, low-noise, single-supply variable gain amplifier (VGA) from Analog Devices. It features a gain bandwidth product of 40 MHz and operates on a single supply voltage ranging from 4.5 V to 5.5 V. The device draws 23 mA of operating current and offers a voltage gain of 34 dB with an input bias current of 400 nA. It is housed in a 16-lead SOIC_N package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel linear-in-dB variable gain architecture for precise signal control
• Low noise performance optimized for high-fidelity signal processing
• Single-supply operation simplifying power management requirements

Applications

• Wireless communication systems requiring wide dynamic range
• Instrumentation amplifiers needing accurate gain adjustment
• Test and measurement equipment demanding low distortion

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Ensure the specific suffix matches the required packaging format. Check for obsolescence notices or lifecycle changes before finalizing procurement plans. Validate electrical parameters against the latest datasheet revisions.

Selection Notes

Select this component when dual-channel VGA functionality is required within a single package. Consider the 40 MHz bandwidth limit for frequency-sensitive applications. Evaluate the single-supply constraint against system power architecture. Compare input bias current specifications with other available options for precision requirements.

Part Context

This part belongs to the AD605 series of variable gain amplifiers designed by Analog Devices. It shares architectural similarities with other members like the AD605BR but differs in packaging and reel configuration. The series is characterized by its linear-in-dB gain response and low noise profile, making it suitable for RF and IF stages.

Replacement Considerations

Direct substitutes include AD605ARZ-R7 and AD605BN variants. Verify pin compatibility and electrical parameter equivalence before substitution. Cross-reference datasheets for any differences in thermal performance or package dimensions.
