AD605BN

Overview

The AD605BN is a dual, low-noise, single-supply variable gain amplifier from Analog Devices. It features two independent linear-in-dB channels with a gain bandwidth product of 40 MHz and a slew rate of 170 V/us. The device operates on a single supply voltage ranging from 4.5 V to 5.5 V, consuming 18 mA of operating current. It is housed in a 16-pin PDIP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual independent linear-in-dB channels for precise gain control
• Low noise performance suitable for sensitive signal applications
• Single-supply operation simplifying power system design

Applications

• RF receiver front-end stages
• Automatic gain control (AGC) systems
• Instrumentation signal conditioning

Procurement Notes

Verify the obsolete status of the AD605BN before procurement planning. Confirm availability through authorized distributors or surplus suppliers. Ensure compatibility with existing 16-pin DIP footprints and single-supply voltage requirements during integration.

Selection Notes

Select this component when dual-channel linear-in-dB gain control is required within a 40 MHz bandwidth. Consider the 16-pin DIP package constraint and single-supply voltage range of 4.5V to 5.5V. Evaluate noise specifications against application sensitivity requirements.

Part Context

The AD605 belongs to the X-AMP series of variable gain amplifiers. It provides dual-channel functionality with linear-in-dB response characteristics. The BN suffix indicates a plastic dual in-line package variant designed for through-hole mounting applications.
