ADG507AKR

ADG507AKR Description

The ADG507AKR from Analog Devices Inc. is a high-performance dual 8:1 analog multiplexer/demultiplexer designed for precision signal routing in demanding applications. Housed in a 28-pin SOIC package, this IC features low on-resistance (300Ω max) and excellent channel matching (ΔRon 15Ω), ensuring minimal signal distortion. It operates with dual (±10.8V to ±16.5V) or single (10.8V to 16.5V) supplies, making it versatile for mixed-voltage systems. Despite its obsolete status, the ADG507AKR remains a reliable choice for legacy designs due to its low leakage current (1nA max) and fast switching (300ns max).
