Hello Ivan-san,
In the case of TPA4411 datasheet, we can find the specification as "Maximum capacitive load 400PF" .
What about TPA614x family's capacitive load drivability specification?

Hi David,
Old amplifiers like TPA6100A2 or TPA4411 have very low power consumption. Although the tradeoff would be that these are not GND centered devices, so considerably big capacitors are required at the outputs, and also you should take care of…
Other Parts Discussed in Thread: TPA4411 , TPA6130A2 Hi,
Could you please give us the frequency response for TPA6130A2 like that "GAIN AND PHASE vs FREQUENCY" which is mentioned on page 14 of TPA4411 data sheet since our customer would like to grasp…

Other Parts Discussed in Thread: TPA4411 , TPA6130A2 APA (audio power amplifier) outputs are sometimes connected to other voltage sources (APAs or power supplies), by design or mistake. If the connected source can force enough voltage at an APA output…
Hi Don-san,
Unfortunately, our customers require 1.8V for the minimum power supply voltage. And we also suggest TPA4411 to them. Could you please offer a graph of characteristics of TPA6100A2 as soon as possible? I am looking forward to your reply.…
Hi Takishin,
I think there should be no problem by adding a detection circuit at the output of TPA6130A2 while it is active. Although you must take care of the current and the voltage that will be present at the output of the amplifier. Attached is…
Hi Dan,
Have the customer actually tested this connection at the output? Amplifier outputs are not 3.3V tolerant, actually they can only reach HPVDD and HPVSS which is around +/-1.8V, so connecting output to 3.3V is not a safe condition. Regarding the…
