ADG608BR

ADG608BR Description

The ADG608BR from Analog Devices Inc. is a high-performance 8:1 analog multiplexer/demultiplexer IC designed for precision signal routing in demanding applications. Housed in a 16-pin SOIC package, it features low on-state resistance (30Ω max) and minimal channel-to-channel matching (ΔRon ≤ 5Ω), ensuring consistent signal integrity. With dual supply voltage support (±5V) or single supply (3.3V to 5V), it accommodates a wide range of system requirements. The device is optimized for low leakage (500pA max) and fast switching (75ns Ton, 45ns Toff), making it suitable for high-speed data acquisition and signal processing.

ADG608BR Features

• Low On-Resistance: 30Ω max reduces signal attenuation and distortion.
• Fast Switching: 75ns/45ns (Ton/Toff) enables rapid signal routing.
• Low Leakage Current: 500pA max ensures minimal power loss in off-state.
• Dual/ Single Supply Operation: Supports ±5V or 3.3V–5V for flexible integration.
• Low Charge Injection: 6pC minimizes glitches during switching.
• Low Capacitance: 9pF (CS(off)), 40pF (CD(off)) reduces crosstalk and signal degradation.
• 8:1 Configuration: Ideal for multiplexing/demultiplexing analog/digital signals.

ADG608BR Applications

• Data Acquisition Systems: High-speed signal routing with minimal distortion.
• Test & Measurement Equipment: Precision switching for automated test systems.
• Medical Instrumentation: Low-leakage performance for sensitive signal paths.
• Communication Systems: Multiplexing in RF and baseband signal chains.
• Industrial Control: Reliable switching in harsh environments due to robust design.

Conclusion of ADG608BR

The ADG608BR excels in applications requiring low distortion, fast switching, and high precision. Its low Ron, minimal leakage, and dual/single supply flexibility make it superior to generic multiplexers, particularly in high-frequency and low-power systems. Though marked obsolete, its performance remains relevant for legacy designs or systems prioritizing signal fidelity. Engineers should consider alternatives for new designs but can rely on the ADG608BR for proven performance in critical analog switching tasks.
