    Lis-san, I could simulate case of RL = 10kohm and confimed load current. So please close this thread. BR,

  • OPA209 unity gain oscillation

    Other Parts Discussed in Thread: LM7301 , OPA209 Hi, I am using an OPA209 to build a 2.5V voltage reference. I use two 10kohm resistors to divide the 5V supply voltage and send it to the non-inverting input of an OPA209. The inverting input is shorted…

  • RE: TL034: How to calculate the offset voltage

    Resolved
    User, I suggest increasing the Vos manually. Kai, op amp in last question was OPA209 (not 207)

  • RE: OPA2209: OPA2209 delay issue for current sense application

    Hi Red, All of Kai's points regarding the circuit's response time are spot on and should be followed. And indeed, I would recommend splitting the high gain up evenly among two amplifier stages. It is interesting that the design sets a high gain…
