MEGO Dual Module

Simple module to provide a convenient solution for splitting a single rail voltage into both positive and negative voltages.

Why do we need to split voltage into positive and negative

We need to split voltage into positive and negative in electronics because certain circuits and components require a dual (bipolar) power supply to function properly.

1. Operational Amplifiers (Op-Amps)

• Many op-amps require dual power supplies (e.g., ±12V or ±5V) to operate properly in both positive and negative voltage ranges.

• Without a split rail, the op-amp would be limited to unipolar operation, which restricts certain signal processing applications.

2. Analog and Audio Circuits

• Many analog signal processing circuits, such as audio amplifiers and sensor circuits, require a reference at 0V (ground) while needing both positive and negative supply rails.

• This ensures symmetrical signal swings in AC-coupled systems, preventing distortion.

3. Microcontroller & Digital Logic Applications

• Some systems integrate both analog and digital components, where the analog section requires a split rail voltage.

• It simplifies mixed-signal designs when interfacing with DACs (Digital-to-Analog Converters) or ADC (Analog-to-Digital Converters).

4. Powering Sensors & Measurement Equipment

• Some specialized sensors and precision measurement equipment need ± voltages to function correctly.

• Using a voltage-splitting module avoids the need for an extra power supply.

5. Convenience in Prototyping and Lab Work

• Instead of using a dedicated dual power supply, a simple module can provide ±V from a single source, making it more compact and easier to use.

• This is useful for battery-powered applications where a dual supply is impractical.

Instruction of How to use a MEGO Dual Module

so we will demonstrate how to use MEGO Dual

1

To use the MEGO Dual, start by connecting any compatible power source via a Type-C cable. Once powered, the +5V red indicator should light up.

2

To select the voltage output type, move the 5-way toggle switch left or right to choose between positive (+) or negative (-) voltage.

3

Adjust the voltage rating by moving the toggle switch up or down as needed.

4

Press inward on the 5-way toggle switch to confirm your selected voltage rating, and use the ON/OFF control to activate or deactivate the output.

5

When turned ON, the corresponding channel is active. If you require both positive and negative voltages, ensure that both channels are turned ON.
