AD7506JN

AD7506JN Description

The AD7506JN from Analog Devices Inc. is a high-performance 16:1 analog multiplexer/demultiplexer designed for precision signal routing in demanding applications. Housed in a 28-pin DIP package, this IC features a low on-state resistance (Ron) of 450Ω (max) and excellent channel-to-channel matching (ΔRon) of 18Ω, ensuring minimal signal distortion. With a dual supply voltage range of ±15V, it supports bipolar signal switching, making it suitable for both industrial and instrumentation systems. The device offers fast switching times (Ton = 1.5µs, Toff = 1µs) and low parasitic capacitance (5pF CS(off), 40pF CD(off)), enhancing high-frequency performance. Though marked Obsolete, its robust design remains relevant for legacy systems.
