MAX319CSA

MAX319CSA Description

The MAX319CSA from Analog Devices Inc./Maxim Integrated is a high-performance SPDT (Single Pole Double Throw) analog switch designed for precision signal routing in demanding applications. Housed in an 8-pin SOIC package, this IC offers low on-resistance (35Ω max), minimal leakage current (250pA max), and fast switching speeds (175ns Ton, 145ns Toff). It operates over a wide single-supply voltage range (10V to 30V) or dual-supply (±4.5V to ±20V), making it versatile for both industrial and consumer electronics. With low charge injection (3pC) and matched channel resistance (ΔRon ≤ 2Ω), it ensures minimal signal distortion, ideal for high-accuracy systems.
