DG412DY+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412DY+ is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a normally open (NO) configuration and operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. The device utilizes a 44V silicon-gate process for robust performance. Key electrical parameters include a maximum on-resistance of 45Ω, an on-resistance match between channels of 3Ω max, and guaranteed on-resistance flatness of Δ4Ω max over the signal range. Switching times are typically 175ns for turn-on and 145ns for turn-off. It offers low charge injection of 10pC max, off-leakage current less than 5nA at +85°C, and an ESD tolerance of 2000V minimum per Method 3015.7.

Ensure compatibility with required voltage levels and logic interfaces before integration. Confirm RoHS compliance status through authorized distributors or direct manufacturer channels.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST normally open analog switch is required. Consider the 45Ω maximum on-resistance and switching speeds for signal integrity requirements. Verify that the operating temperature range and supply voltage constraints align with the system design specifications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG411/DG412/DG413 series of improved, quad, SPST analog switches. The DG412 specifically provides a normally open configuration, distinguishing it from the DG411 (normally closed) and DG413 (mixed NC/NO). These devices serve as drop-in replacements for older industry-standard models while offering enhanced electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference in logic between the DG412 and DG411?

The DG412 is a normally open (NO) switch, meaning the switch closes when the input is high. The DG411 is a normally closed (NC) switch, which opens when the input is high.

How does the DG412 handle electrostatic discharge?

The device guarantees an ESD tolerance of 2000V minimum per Method 3015.7.

What is the maximum on-resistance flatness specified for this device?

The on-resistance flatness over the signal range is guaranteed to be Δ4Ω max.
