I have a PWB with the circuit shown for the TPA3122D2EVM board and it sounds very good. For the inductor it uses the following from DigiKey: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=811-2081-ND and I run the board at 12 volts…
Other Parts Discussed in Thread: TPA3122D2 I've built an audio amplifier based on TPA3122D2 and it sound is very good.
I've two questions:
the 10uF capacitor connected to pin 17 and ground (see figure 28 datasheet) i not find a ceramic or polyester…
Part Number: TPA3116D2 Other Parts Discussed in Thread: TPA3122D2 , , TPA3123D2 Hi,
Is there a simple way of getting closer to a 50% duty cycle? Its slightly off that a fluke meter can pick up. I am now running in BTL mode, so that did help reduce the offset…
Other Parts Discussed in Thread: TPA3122D2 , PCM1865 , PCM1863 , PCM1861 , PCM9211 Here is what I am trying to do... Convert an audio signal to a PWM signal, invert and buffer this signal so it can be sent to a remote location using unshielded twisted pair…
Hi Namith, May I know where is the heat from? From AMP or inductors or other components? We know that some customer had the similar heat issue previously, and the root cause is the caps failure on the board. Please help to check the component failure/wrong…
Hi Tom,
You are correct, the LM475x is only available in the TO263 SMT package. Is the application one in which through-hole is required? If so, you might consider the TPA3122D2, which does come in a PDIP package : http://www.ti.com/docs/prod/folders…
Other Parts Discussed in Thread: TPA3123D2 , TPA3124D2 , TPA3125D2 , TPA3122D2 , DRV134 , NE5532 , TL072 Hello,
I am attempting to create an amplifier with an output of 20-25w into an 8ohm load. The IC I am using to attempt this is the TPA3123D2 in BTL mode…
Hi Alain,
Thanks for your question. I have a a few questions regarding your test setup.
Did you measure the quiescent current using the TPA3122D2 EVM? If you are not using EVM, what is the output filter used? What is the voltage on the SDZ and MUTE…
