  • LM4950: About capacitors

    Part Number: LM4950 Tool/software: Hi,all Let me ask a question about LM4950? Can I connect polar electrolytic capacitor to a output such as LM4950? Further ahead is a speaker. I am looking forward to your reply. Best regards. YasumasaＢ

  • LM4950: Two POP sounds are generated when the chip is powered on

    Part Number: LM4950 Tool/software: Dear Engineer: When I used your company's LM4950 amplifier chip, I found that two pop sounds were generated when it was turned on, and there were two situations for the first pop sound. The first situation is shown…

  • LM4950: power dissipation

    Part Number: LM4950 Hello Experts, I have some question as follows. Would you answer it, please? 1. Regarding equation 4, it seems max power dissipation of mono-BTL configuration. How about SE configuration? 2. Regarding equation 5, it seems TA max of…

  • 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…
