  • ALM2403-Q1: power dissipation calculation

    Resolved
    Part Number: ALM2403-Q1 Hello PRAMP team, I got a question about power dissipation in the datasheet P18. We assume the definition of V+ & VO(X) as below. V+ ： VS+ voltage VO(X) ： OUT(1)-OUT(2) = Vp-p Threfore, For example at below figure; We set that…

  • RE: ALM2403-Q1: Overvoltage protection for ALM2403Q1 output shortcut to 36V

    Resolved
    Hi Jin, Jin Huang said: I tried with 10µF in loop, without any resistors (instead of 1k//10µF), then I didn't get any signal. Why? You need to DC biasing for the feedback. Without the 1k resistor or similar, you do not have DC biasing voltage in the…
