ADG658YRU

ADG658YRU Description

The ADG658YRU 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 TSSOP package, this device features an exceptionally low on-state resistance (Ron) of 75Ω (max) and minimal channel-to-channel matching (ΔRon) of 1.3Ω, ensuring consistent signal integrity. With a wide supply voltage range (±2V to ±6V dual or 2V to 12V single), it accommodates both single and dual-supply systems. The ADG658YRU is optimized for low leakage (200pA max) and fast switching (115ns Ton, 45ns Toff), making it ideal for high-speed, low-power applications.

ADG658YRU Features

• Low On-Resistance: 75Ω (max) ensures minimal signal attenuation.
• High Bandwidth: -3dB bandwidth of 210MHz supports high-frequency signals.
• Low Charge Injection: 2pC reduces glitches during switching.
• Low Capacitance: 4pF (CS(off)), 23pF (CD(off)) minimizes crosstalk.
• Dual/ Single-Supply Operation: Compatible with ±2V to ±6V or 2V to 12V supplies.
• Robust Performance: 1.3Ω channel matching and 200pA leakage enhance precision.
• Fast Switching: 115ns (Ton), 45ns (Toff) for rapid signal routing.

ADG658YRU Applications

The ADG658YRU excels in applications requiring high-speed, low-distortion signal switching, such as:

• Test & Measurement Equipment: Precision signal routing in oscilloscopes and data acquisition systems.
