  • LM4950: power consumption for 1-channel output(SE)

    Resolved
    Part Number: LM4950 Tool/software: Hi, I think Figure 49 is a graph for 2-channel output(SE). If this is correct, how should we consider the power consumption for 1-channel output(SE)? Can we consider it to be half the value of Figure 49? Best Regards…

  • RE: LM4950: LM4950 dead after short circuit

    Resolved
    Hi Richard, It seems LM4950 can be damaged due to short circuit in some cases, you can refer to this old thread: LM4950 blew up when both outputs shorted to Ground. - Audio forum - Audio - TI E2E support forums . As mentioned, this is most likely damaged…

  • LM4950: DC Bias on one channel of the amplifier after the capacitor but not the other?

    Part Number: LM4950 Tool/software: I am using the LM4950 in SE configuration with an AC coupling cap at the output, the signal is driven across an 8 Ohm load and then into a 100mOhm low side current sense resistor. I find that one channel consistently…
