Transformers for splitting
LL1570 and LL1570XL
The LL1570 is designed for splitting signals in application where large ground differences may appear, but is also very
useful as a general purpose audio transformer. By careful design, the capacative coupling between the different part of
the transformer is kept to a minimum. The three-section winding structure which is necessary for decoupling also results
in a very high bandwidth. The transformer is built up from two coils, each with primary and secondary windings
separated by electrostatic shields, and a high permeability mu-metal core. The two coil structure in combination with the
mu-metal can results in high immunity to external magnetic fields.
In the LL1570XL, the core is about 45% larger than in the LL1570, resulting in a larger level capability.
