TYPICAL CHARACTERISTICS
Note 1. Input coupling 1
µF capacitors are used for all measurements.
2. Differential inputs are applied and BTL outputs are measured.
3. Balanced LC filter is used for THD+N measurement and power efficiency measurement.
4. Characteristic frequency of the LC filter is set 41KHz unless otherwise specified.
