ADG608TRU

ADG608TRU Description

The ADG608TRU from Analog Devices Inc. is an 8:1 single-channel analog multiplexer/demultiplexer designed for precision signal routing in low-voltage applications. Housed in a 16-pin TSSOP package, this IC offers low on-state resistance (30Ω max) and minimal charge injection (6pC), making it ideal for high-accuracy signal switching. With a dual supply voltage range of ±5V or a single supply of 3.3V to 5V, it supports both bipolar and unipolar operation. Although marked as obsolete, its performance metrics remain competitive for legacy designs.

ADG608TRU Features

• Low Leakage Current: Max 500pA ensures minimal signal distortion in high-impedance circuits.
• Fast Switching: 75ns (Ton) and 45ns (Toff) enable rapid signal routing.
• Channel Matching: ΔRon of 5Ω (max) reduces signal path variations.
• Low Capacitance: 9pF (CS(off)) and 40pF (CD(off)) minimizes crosstalk and bandwidth limitations.
• Robust Packaging: MSL 1 (Unlimited) rating ensures reliability in storage and handling.
• Low Power Operation: Compatible with 3.3V/5V systems, suitable for battery-powered devices.

ADG608TRU Applications

• Test & Measurement Equipment: Precision signal routing in data acquisition systems.
• Medical Instrumentation: Low-noise switching for sensor interfaces.
• Audio/Video Switching: High-fidelity signal multiplexing in AV systems.
• Industrial Control Systems: Reliable operation in harsh environments.
• Legacy Designs: Replacement or maintenance of older systems requiring ±5V operation.

Conclusion of ADG608TRU

The ADG608TRU excels in low-voltage, high-precision applications with its low Ron, fast switching, and excellent channel matching. While obsolete, its low leakage and robust performance make it a viable choice for legacy or niche designs. Engineers seeking reliable analog switching in 3.3V/5V or ±5V systems may still find value in this IC for critical signal-path applications.
