Key Features
- 4 independent SPST channels in a 16-pin SOIC package enable compact quad-channel analog signal switching
- Compatible with 3 V, 5 V, and 9 V supply rails for flexible integration in mixed-voltage analog front ends
- Low on-resistance (typically 35 Ω) minimizes signal attenuation in precision analog mux and routing circuits
- TTL/CMOS logic-level control inputs allow direct interfacing with 3.3 V and 5 V microcontrollers without level shifters
Applications
The DG413LDY-E3 is used in data acquisition systems, audio signal routers, and test-and-measurement equipment where four independent analog channels must be switched under digital control with minimal signal distortion. Its support for 3 V, 5 V, and 9 V supplies makes it versatile across battery-powered portable instruments and industrial analog front ends. The SOIC-16 package enables dense PCB placement in multi-channel signal conditioning circuits.

Frequently Asked Questions
How many independent switch channels does the DG413LDY-E3 provide, and what supply voltages does it support?
The DG413LDY-E3 contains 4 independent SPST analog switch channels housed in a 16-pin SOIC package. It operates from single-supply voltages of 3 V, 5 V, or 9 V, or dual supplies up to ±9 V, covering a wide range of analog signal switching applications.
What is the on-resistance of the DG413LDY-E3 and how does it affect signal quality in audio routing?
The DG413LDY-E3 has a typical on-resistance of approximately 35 Ω, which when combined with a high-impedance load (>10 kΩ) introduces less than 0.35% signal attenuation. This low on-resistance and flat resistance vs. signal voltage characteristic make it suitable for audio multiplexing with low distortion below 0.01% THD.
Can the DG413LDY-E3 be directly controlled by a 3.3 V microcontroller GPIO?
Yes, the DG413LDY-E3 logic control inputs are TTL/CMOS compatible, accepting logic-high thresholds as low as 2.4 V when operated from a 5 V supply, allowing direct 3.3 V GPIO control from modern microcontrollers. Each of the 4 channels is controlled by an independent digital input with propagation delays typically under 100 ns.
In what test-and-measurement or data acquisition scenarios does the DG413 quad switch outperform mechanical relays?
In automated test equipment scanning up to 4 analog channels, the DG413LDY-E3 switches in under 100 ns versus mechanical relay switching times of 1 ms to 10 ms, enabling scan rates above 1 MHz. It also eliminates contact bounce, offers 5 billion switching cycles lifetime, and consumes under 1 mW quiescent power compared to hundreds of milliwatts for relay coils.
