LUNDAHL DIGITAL AUDIO TRANSFORMERS

A range of transformers designed specifically for digital audio. All have a relatively large amorphous metal core, and thus have low copper resistance, high signal tolerance and low internal capacitance. All these designs must be protected from DC current. Pin diameters are 1.1mm, recommended PCB drill 1.5mm.
Full data and application notes for each type are available from the Lundahl website at www.lundahl.se, or from Canford Technical Support.

LL1572 Isolation Transformer

Suitable for drive and reception of a balanced line, with both source and receive impedances of either 75 or 110 ohms. Turns ratio: 1:1. Dimensions: 15(l) x 9(w) x 11(h above PCB)mm. Weight 2g.

LL1573 Two Output Splitting Transformer

For two way splits of a digital audio signal, with both source and receive impedances of either 75 or 110 ohms. Turns ratio: 1:1:1. Dimensions: 15(l) x 9(w) x 12(h above PCB)mm. Weight 2.3g.

LL1589 Three Output Splitting Transformer

For three way splits of a digital audio signal, with both source and receive impedances of either 75 or 110 ohms. Turns ratio: 1:1:1:1. Dimensions: 15(l) x 12(w) x 12(h above PCB)mm. Weight 2.5g.

LL1574 Impedance Matching Transformer

Suitable for interfacing between 110 ohm AES/EBU (4Volt) and 75 ohmDATS/AES3id (1Volt) networks. Turns ratio: 1:1.2 . Dimensions: 15(l) x 9(w) x 11(h above PCB)mm. Weight 2g.
