LL1582 is an audio output transformer for balanced or unbalanced drive, with the following features: 1. Pin compatible with the popular LL2811 2. With internal shields to improve common mode passthrough rejection. This is important in analog output from digital systems. 3. Suggested use: 2 : 1 (secondaries in parallel) with e.g. NE5532 op amps for low noise. 4. Precision made audio C core for small size. 5. Two-coil structure and mu-metal housing for high magnetic noise immunity. 6. Designed to fit three in a row across a Euroboard. The secondaries can be connected in parallel for low output impedance or in series for high output level.
