UBC-01 Audio Balanced Driver - Unbalanced to Balanced  Click on the picture to get a larger view. This design is very well suited for connecting two power amplifiers in bridge mode. Interesting features- 2-layer pcb with 35 um copper.
- Gold pads.
- Extremely low distortion.
- High common mode output impedance.
- Low and adjustable differential mode output impedance.
- Option for DIL08 or SO08 DRV134/135 .
- Several types of input coupling capacitors, high performance RIFA PHE426 polypropylene or 5 mm/ 0.2" caps such as polyester or other types with the same footprint, or some other type with pin spacing from 15 to 27.5 mm.
- On-board regulators of LM317/337 type
- Discrete regulators for using higher voltage than the max supply voltage of the LM317/337.

I have uploaded a complete set of files for the SSR-01 The file kit contains schematics for the whole design bit also eleven different versions where I have made schematics for each version and also a BOM. At the moment I have versions for 5, 9, 12, 15, 18 and 24 V with LM431 as voltage reference and 9, 12, 15, 18 and 24 V with LM329. |
