ADG409BRUZ

Analog Devices ADG409BRUZ is a monolithic CMOS analog multiplexer designed for high performance signal routing. It features two independent SP4T switches in a 4:1 differential configuration, allowing one of four differential inputs to be connected to a common differential output. The device operates with a dual supply voltage of ±15V and consumes low power with a supply current of less than 75 µA. It offers low on-resistance of 100 Ω maximum, with channel-to-channel matching of 15 Ω, ensuring minimal signal distortion. The switch exhibits low leakage current of 500 pA and charge injection of 20 pC, making it suitable for precision applications. Crosstalk is -85 dB at 100 kHz, providing good isolation between channels.

The device is designed on an enhanced LC²MOS process, providing fast switching speed and break-before-make switching action, which prevents momentary shorting of channels. The operating temperature range is -40°C to 85°C, allowing use in industrial environments. The ADG409BRUZ is packaged in a 16-TSSOP (0.173", 4.40mm width) surface mount package, ideal for compact PCB designs. The multiplexer is controlled by 2-bit binary address lines (A0, A1) and an enable input (EN).

Typical applications include audio and video routing, automatic test equipment, data acquisition systems, battery-powered systems, and communication systems. The device is a plug-in replacement for DG408/DG409 multiplexers.
