设置TAS5548的EQ后无输出

Other Parts Discussed in Thread: TAS5548

我将TAS5548应用在纯数字音频放大器产品时,按官方datasheet未能成功打开EQ功能,在做如下设置后,放大器无输出。

0x89  =  00 00 00 00 00 00 00 00(使能CH1 TREBLE & BASS fuction)

0x8A  =  00 00 00 00 00 00 00 00(使能CH2 TREBLE & BASS fuction)

0x51  = 00 80 16 15 ff 00 6b f5 00 74 7e db 00 ff 94 0b ff 80 6b 0f (CH1 BQ section1)

0x52  = 00 69 67 8f ff ba df 39 00 00 00 00 00 5b b9 37 00 00 00 00(CH1 BQ section2)

0x58  = 00 80 16 15 ff 00 6b f5 00 74 7e db 00 ff 94 0b ff 80 6b 0f (CH2 BQ section1)

0x59  = 00 69 67 8f ff ba df 39 00 00 00 00 00 5b b9 37 00 00 00 00(CH2 BQ section2)

0x51,0x52,0x58,0x59 的BQ设置参考TAS5508的Country96.EQ550X设置。

请问,上述设置是否正确,或还有其它寄存器地址需要设置?如果不使用EQ功能,电路工作正常。
