Maxim Integrated's DG412EUE+T: High-Performance Analog Multiplexer

The DG412EUE+T from Maxim Integrated is a precision monolithic quad analog switch designed to provide high-performance switching of analog signals. Combining low power consumption with high switching speed, this device is an ideal choice for a wide range of applications, including data acquisition systems, communication systems, and sample-and-hold circuits.

Constructed with Maxim's proprietary silicon-gate process, the DG412EUE+T offers significant improvements over older CMOS designs. This includes enhancements in switch on-resistance, conductance, and charge injection. The device operates with a single positive supply or a bipolar supply, with a specified range from +10V to +30V, or ±4.5V to ±20V, which provides flexible options for various circuit designs.

Each switch of the DG412EUE+T can handle continuous current up to 30mA, and the device features a low on-resistance of typically 100 ohms. This low on-resistance is matched between switches to within 5 ohms over the full signal-input range, ensuring excellent signal integrity and minimal signal attenuation.

The DG412EUE+T also boasts fast switching times, with turn-on time typically at 175ns and turn-off time around 145ns, making it suitable for high-speed operations. In addition, the device has a low charge injection of typically 15pC, which minimizes distortion and allows for more accurate signal processing.

For added safety and reliability, the DG412EUE+T features overvoltage protection at the switch inputs. Signals up to +35V or -35V can be withstood by the off switches without damage, providing robustness against unexpected voltage spikes.

Maxim Integrated's DG412EUE+T comes in a 16-pin TSSOP package, which is surface-mountable and suitable for compact PCB layouts. The device's enhanced ESD protection makes it more resistant to electrostatic discharges, ensuring longevity and stable performance in sensitive electronic equipment.

Whether used in test equipment, audio signal routing, or precision analog signal processing, the DG412EUE+T stands out as a high-quality, reliable solution for your analog switching needs.
