13 AC CHARACTERISTICS
Notes
1. VP = ±25 V; RL =4 ;fi = 1 kHz; fosc = 310 kHz; Rs = 0.1 (series resistance of lter coil);Tamb =25 °C; measured
in reference design (SE application) shown in Fig.7; unless otherwise specified.
2. Indirectly measured; based on Rds(on) measurement.
3. Total Harmonic Distortion (THD) is measured in a bandwidth of 22 Hz to 22 kHz. When distortion is measured using
a low-order low-pass filter a significantly higher value will be found, due to the switching frequency outside the audio
band.
4. Efficiency for power stage; output power measured across the loudspeaker load.
5. VP = ±25 V; RL =8 ;fi = 1 kHz; fosc = 310 kHz; Rs = 0.1 (series resistance of lter coil);Tamb =25 °C; measured
in reference design (BTL application) shown in Fig.4; unless otherwise specied.
