ADG439FBRZ

ADG439FBRZ Description

The ADG439FBRZ from Analog Devices Inc. is a high-performance, dual 4:1 single-pole four-throw (SP4T) analog switch designed for precision signal routing in demanding applications. Housed in a 16-SOIC package, it features low on-state resistance (270Ω typ) and minimal channel-to-channel matching (ΔRon of 8.1Ω), ensuring consistent signal integrity. With dual ±15V or single +15V supply operation, it supports a wide range of analog and mixed-signal systems. The device boasts ultra-low leakage current (500pA max) and low charge injection (15pC), making it ideal for high-accuracy applications. Its fast switching times (230ns Ton, 130ns Toff) and low capacitance (3pF CS(off), 22pF CD(off)) further enhance performance in high-speed environments.
