ADG608BRU

ADG608BRU Description

The ADG608BRU from Analog Devices Inc. is a high-performance 8:1 analog multiplexer/demultiplexer designed for precision signal routing in demanding applications. Housed in a compact 16-pin TSSOP package, this IC offers low on-state resistance (30Ω max) and excellent channel-to-channel matching (ΔRon ≤ 5Ω), ensuring minimal signal distortion. It operates with single-supply (3.3V to 5V) or dual-supply (±5V) configurations, making it versatile for mixed-voltage systems. Although marked as obsolete, its robust design remains relevant for legacy or specialized systems requiring reliable switching performance.

ADG608BRU 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 during switching, critical for precision analog systems.
• Low Capacitance: 9pF (CS(off)) / 40pF (CD(off)) minimizes crosstalk and signal degradation.
• Wide Supply Range: Supports ±5V dual or 3.3V/5V single-supply operation for flexibility.
• High Channel Matching: 5Ω max ΔRon ensures consistent performance across all channels.

ADG608BRU Applications

• Test & Measurement Equipment: Ideal for automated test systems (ATE) due to low distortion and fast switching.
• Data Acquisition Systems: Ensures accurate signal routing in multi-channel ADC/DAC interfaces.
• Medical Instrumentation: Low leakage and high reliability suit patient monitoring devices.
• Industrial Control Systems: Robust performance in harsh environments with ±5V supply tolerance.
• Audio/Video Switching: Low capacitance and charge injection preserve signal integrity in AV routing.

Conclusion of ADG608BRU

The ADG608BRU excels in applications demanding low noise, fast switching, and precision signal routing. While obsolete, its low on-resistance, excellent channel matching, and dual-supply capability make it a preferred choice for legacy designs or systems requiring high-performance analog switching. Engineers in test, medical, and industrial sectors can leverage its reliability for critical signal-path applications.
