TAS5132DDV6EVM Performance
Channel separation is tested for two channels in a different package, channel 4 and channel 5. A 4- Ω load
is used for channel 4 SE; an 8- Ω load is used for channel 5 BTL. The channel 5 input signal is 0 dBFS;
channel 4 is muted. Reference voltage is 11.19 Vrms. Shielded output inductors provide better channel
separation.
Figure 17. Channel Separation (4-5)
Channel separation is tested for two channels in the same package, channel 5 and channel 6. Eight-ohm
loads are used for both channels. The channel 5 input signal is 0 dBFS; channel 6 is muted. Reference
voltage is 11.19 Vrms.
