AD7506KN

AD7506KN Description

The AD7506KN 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. Operating with a dual supply voltage of ±15V, it supports bidirectional signal flow and is optimized for low leakage currents (5nA max) and fast switching (1.5µs Ton, 1µs Toff). With a channel capacitance of 5pF (CS(off)) and 40pF (CD(off)), it minimizes crosstalk and preserves signal integrity.
