MAX333CWP

MAX333CWP Description

The MAX333CWP from Analog Devices Inc./Maxim Integrated is a high-performance, quad SPDT (Single Pole Double Throw) analog switch designed for precision signal routing in demanding applications. Housed in a 20-pin SOIC package, this IC features low on-resistance (250Ω max) and ultra-low leakage current (5nA max), ensuring minimal signal distortion and power loss. It supports dual (±5V to ±18V) or single (10V to 30V) supply voltages, offering flexibility in mixed-voltage systems. With fast switching times (1µs turn-on, 500ns turn-off) and low channel capacitance (5pF), the MAX333CWP excels in high-speed signal multiplexing and demultiplexing tasks.

MAX333CWP Features

• Low On-Resistance: 250Ω max ensures minimal voltage drop and signal attenuation.
• Ultra-Low Leakage: 5nA max leakage current enhances signal integrity in precision circuits.
• Wide Supply Range: Supports ±5V to ±18V (dual) or 10V to 30V (single), ideal for mixed-voltage designs.
