The Question Of TAS5706A Of Output Voltage Vs Dynamic Frequency Range

Other Parts Discussed in Thread: TAS5706A

Hi，

my PCB was designed after referencing TAS5706EVM2. It work in BTL mode .PVCC is 18V .volume gain is 0 dB. the load resistance is 7.7 Ohm.

I experience some questions when I keep other measurement condition unchanged ，except for frequency.

The following is my measurement  record

frequency（KHZ）                            0.02,1,10,16

output Voltage of TAS5706A（Vrms）9.15,9.85,8.8,7.9

other question：I found second harmonic and  three harmonic at frequency of 10KHZ and 16KHZ when I measure TAS5706A Spectrum with Analyzer

Do you experience the question when you measure TAS5706EVM2？Is my measurement right？
