AD605BRZ-RL

Overview

The AD605BRZ-RL is a dual, low-noise, single-supply variable gain amplifier (VGA) from Analog Devices. It operates on a single 4.5 V to 5.5 V supply and features a 40 MHz gain-bandwidth product with a 170 V/µs slew rate. The device provides a selectable voltage gain range of either -14 dB to +34 dB or 0 dB to +48 dB via an external resistor. It draws 23 mA of operating current and functions within a temperature range of -40 °C to +85 °C. Packaged in a 16-pin SOIC for surface mount applications.

Feature Summary

• Dual-channel architecture with independent signal processing paths
• Linear-in-dB gain control using a single unipolar voltage input
• Configurable gain range selection through external feedback resistance
• Low noise performance optimized for wideband signal applications

Applications

• Medical imaging systems requiring high dynamic range signal conditioning
• Wireless communication infrastructure for automatic gain control
• Industrial automation sensors needing precise amplitude modulation

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with the required operating temperature range and supply voltage constraints before integration. Cross-reference the part number with authorized distributors to confirm current availability status and authenticity.

Selection Notes

Select this component when dual-channel linear-in-dB amplification is required with minimal external calibration. Consider the 40 MHz bandwidth limit for high-frequency signal integrity. Evaluate the single-supply operation benefits against system power constraints. Verify that the 16-pin SOIC footprint aligns with the target PCB layout requirements.
