TYPICAL CHARACTERISTICS

Note 1. Input coupling 1µF 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.
