Description: Burr-Brown DRV134 audio balanced line receiver schematic PCB/kit available? There is an interest in creating a balanced line receiver using the DRV134.
The Burr-Brown DRV134 is an integrated circuit designed for audio applications, specifically for converting unbalanced audio signals to balanced signals. The DRV134 features low distortion and low noise, making it suitable for professional audio equipment. The typical application involves connecting the DRV134 to an unbalanced audio source, which it then processes to produce a balanced output.
To design a balanced line receiver using the DRV134, the following key components and considerations are necessary:
1. **Power Supply**: The DRV134 operates typically from a dual power supply, ranging from ±5V to ±15V. Proper decoupling capacitors (e.g., 0.1 µF ceramic capacitors) should be placed close to the power pins to minimize noise.
2. **Input Configuration**: The unbalanced input can be connected directly to the non-inverting input (pin 2) of the DRV134. A resistor (typically 10kΩ) can be used to ground the inverting input (pin 3) to set the gain of the amplifier.
3. **Output Stage**: The DRV134 provides a differential output. The output pins (pin 6 and pin 7) should be connected to the balanced output line. It is advisable to use a transformer or differential driver circuit at the output to further enhance the signal integrity and reduce common-mode noise.
4. **PCB Layout**: When designing the PCB, it is critical to maintain a compact layout to minimize parasitic capacitance and inductance. The traces connecting the input and output should be kept as short as possible. Ground planes should be utilized to provide a stable reference and reduce electromagnetic interference (EMI).
5. **Testing and Validation**: After assembling the circuit, it is essential to test the performance using an oscilloscope to check for distortion levels and ensure that the output signal maintains the integrity of the original audio input.
By following these guidelines, a functional balanced line receiver using the Burr-Brown DRV134 can be successfully developed, ensuring high-quality audio signal transmission in professional audio applications.Burr-Brown DRV134 AUDIO BALANCED LINE Receiver schematic PCB/Kit anybody?
