The DG308 from Maxim Integrated is a series of high-performance, CMOS analog multiplexers that are designed to provide precision signal routing in a variety of applications. These multiplexers are monolithic, quad, single-pole single-throw (SPST) devices that deliver low on-resistance and low charge injection, making them ideal for data acquisition systems, test equipment, and communication systems.

Key Features

• Low On-Resistance: The DG308 features low on-resistance (R_ON), typically 100Ω, which minimizes signal attenuation and ensures high signal integrity.
• Low Charge Injection: With low charge injection, these multiplexers provide precise signal handling, which is critical for sensitive analog applications.
• Single Supply Operation: The device can operate from a single supply ranging from +10V to +30V or from dual supplies of ±4.5V to ±20V, offering flexibility in various system designs.
• Fast Switching Times: Fast transition times (t_TRANS) of the DG308 ensure responsive performance in applications requiring rapid signal switching.
• TTL/CMOS Compatible: Logic inputs are compatible with TTL and CMOS levels, which allows for easy integration with digital controllers and processors.
• Break-Before-Make Switching: This feature prevents momentary shorting of channels during switching, which is essential for preventing signal corruption.
• ESD Protection: The DG308 includes enhanced electrostatic discharge (ESD) protection, safeguarding the device against static damage during handling and operation.

Applications

The versatility of the DG308 makes it suitable for a wide range of applications, including:

• Data Acquisition Systems
• Audio Signal Routing
• Test Equipment
• Communication Systems
