Part Number: TPA3125D2 Other Parts Discussed in Thread: TPA3122D2 Tool/software: I am considering either TPA3122 or TPA3125 for my hobby project, as I like a DIP (or SO) packages very much, as opposed to thinner pitch ones (I etch my pcbs myself at home…
Part Number: TPA3122D2 hello, I'm using a TPA3122D2 BTL configuration for an amplifier with square wave input. I'm feeding it at 17V and the load is composed of two 4 ohm speakers in series. The problem that I am finding in some parts is that the current…
Hi Petteri, Thanks for the info. Could you please show me the output waveform(both on output pins and after LC filter) when SD is enabled? Is the PWM output still there on the output pins? Could you please also provide the SCH? Is it possibly a solding…
Part Number: TPA3122D2 I'm designing an amplifier with a 12V power rail using the TPA3122 IC with single ended outputs. Using the two gain setting pins (GAIN0 and GAIN1), the gain of the IC can be set to 20dB, 26dB, 32dB, or 36dB. I'm confused on calculating…
Emmett,
There is not special requirement about SRF, as it is more for EMI consideration, usually we think it is higher than 10MHz would be good.
capacitor is important for audio performance THD, usually film capacitor has the best performance. …
Part Number: TPA3122D2 Hi, I'm trying to use the TPA3122D2 to drive a speaker driver in a design. To test it out I purchased components to build the example circuit given here: http://www.ti.com/lit/ug/slou214a/slou214a.pdf (P.4 Figure 3).
I built out…
Part Number: TPA3122D2 Hi,
I was trying to make a portable amplifier using TPA3122. the layout is shown below.
It is not working and oscillates with tick--tick sound.
Please help to fix the problem.
Other Parts Discussed in Thread: TPA3112D1 , TPA3122D2 , TPA3130D2 Hi
i am trying to build power amplifier whose output should be 10-20w to drive the 8 ohms speaker for our active noise control system.
honestly the optimal solution is to find a…
