Other Parts Discussed in Thread: TPA3126D2
Hello expert,
I have 2 questions for TPA3128D2.
First question is regarding input impedance.
Datasheet only said typical input impedance with gain setting. However I'd like to know about min/Max or variation of input impedance of TPA3128D2.
Could you provide it?
Last question is regarding output power rating.
Following figure is comparing chart of output power VS THD of TPA3128D2 and TPA3126D2.
It seems both device can support almost same output power.
However datasheet's AC electric characteristics said TPA3128D2 only support 30W@21V 4ohm load THD10% but TPA3128D2 can support 50W@21V 4ohm load THD10%.
So would you explain about why there is difference between chart and characteristics?
I'm looking forward to hearing back from you.
Best regards,
Kazuki Kuramochi
