Overview

Description

The DG419DY+ is a high-performance analog switch from Maxim Integrated (now part of Analog Devices). It features a single-pole, double-throw (SPDT) configuration, designed for precision signal routing in low-voltage applications.
### Key Features:
- Low On-Resistance: Typically 5Ω (max 25Ω) for minimal signal distortion.
- Fast Switching: <100ns for quick signal routing.
- Wide Voltage Range: Operates from ±4.5V to ±20V (dual supply) or +4.5V to +36V (single supply).
- Low Leakage Current: Ensures high signal integrity.
- TTL/CMOS-Compatible Logic Inputs for easy interfacing.
### Applications:
- Audio/Video switching
- Data acquisition systems
- Test equipment
- Battery-powered devices
The DG419DY+ comes in an 8-pin SOIC package, offering reliable performance in space-constrained designs. Its low power consumption and robust design make it ideal for precision analog switching.
