Line Input Transformer

LL1540

 

LL1540 is a high impedance, high level line input transformer.

The transformer consists of two coils, each with one primary and one secondary part separated by a electrostatic

shield. The core is a high permeability mu-metal core, and the transformer is housed in a mu-metal can.

Being a high impedance transformer, the LL1540 should normally be used in a series-series connection.

Suggested connection for symmetric input

amplifier (recommended for very high CMRR).

Select R for desired input impedance.

With R < 25 k, RC network can be omitted.

Suggested connection for asymmetric input amplifier.

2 x 12 k resistors required for > 60 dB CMRR.
