ADG608BN

ADG608BN Description

The ADG608BN from Analog Devices Inc. is an 8:1 single-channel analog multiplexer/demultiplexer designed for precision signal routing in demanding applications. Housed in a 16-pin DIP (Through Hole) package, this IC offers low on-resistance (30Ω max) and excellent channel matching (ΔRon ≤ 5Ω), ensuring minimal signal distortion. Operating with single-supply (3.3V to 5V) or dual-supply (±5V) voltages, it supports a wide range of analog and digital signals. Though marked Obsolete, its performance remains competitive for legacy systems requiring high reliability.

ADG608BN Features

• Low Leakage Current: 500pA max (IS(off)) ensures minimal power loss in high-impedance circuits.
• Fast Switching: 75ns (Ton) / 45ns (Toff) enables rapid signal routing for time-critical applications.
• Low Charge Injection (6pC): Reduces glitches in sensitive analog circuits (e.g., data acquisition).
• Low Capacitance: CS(off) = 9pF, CD(off) = 40pF minimizes crosstalk and bandwidth limitations.
• Robust Construction: MSL 1 (Unlimited) moisture sensitivity ensures durability in harsh environments.

ADG608BN Applications

• Data Acquisition Systems: Ideal for multiplexing sensor inputs with low distortion.
• Audio/Video Routing: Low charge injection preserves signal integrity in AV switches.
• Test & Measurement Equipment: High-speed switching suits automated test systems.
• Industrial Control: Reliable performance in PLCs and signal conditioning modules.
• Legacy System Maintenance: A dependable choice for repairing/upgrading older designs.

Conclusion of ADG608BN

The ADG608BN excels in precision signal switching with its low Ron, fast response, and minimal leakage. While obsolete, its analog performance and through-hole packaging make it valuable for legacy or rugged applications. Engineers seeking a low-noise, high-speed multiplexer for industrial or test systems may still find it a viable solution despite newer alternatives.
