    Grant Moore
    Hi, I am using the reference design for the TPA3125D2 in BTL configuration with 20Vdc supply and the circuit performs just fine. I would like to drive 4ohm speakers up to 15 watts and when I tested I could get it to put out 10 watts before it would start to shut down. I've paralleled the outputs...

    stan knoblich
    Hello, I would like to know on the outputs of the TAS5717 OUTA,B,C,D, is there a problem with tying the designated minus outputs say B and C together for a common connection? We have a situation where, like a headphone jack, the connections have Right, Left and a common. Will this cause any safety problem...

    Dear Sir, I have a question. In the EVM board Rev.C of TPA3130D2, phenomenon occurs when a current flows through the power input under the condition of no load no input (0.3A input 5V). So, as a result I have to investigate the cause of the problem, the current value is returned to normal by removing...

    Hi , I am evaluating the performance of a project to 450W bass guitar in 4Ohm and I have some doubts on the choice of amplifier used. For now I think I will use the LME49810 LME49830 instead of as it can handle mosfet and thus would have solved the problem of thermal runaway of the BJT , I would like...

    the datasheet is very limited in the spec of this amp TLV1018. what is missing is: capacitive loading vs stability (in case a cable is used) signal polarity (is the gain sign positive or negative) also the input stage is unspecified in terms of dc operating range, spec says it needs an ac coupling...
