  • RE: LM2902-Q1: Output abnormal

    Hi Mike, Ok, thanks! I will apply OPA202 samples for them. If we verify OPA202 is no problem, then the root cause of this issue is output stage of LM2902-Q1. Thanks! Ethan Wen

  • JFE150EVM: PSRR of EVM Circuit

    Part Number: JFE150EVM Other Parts Discussed in Thread: OPA202 , , JFE150 Hi, I note in the JFE150EVM there's an LC on the supply input, with a corner around 1 kHz or so. I'm wondering with 60 dB of gain how sensitive the Figure 4-1 circuit in the JFE150…

  • RE: OPA4180: output swing and power sequence problem

    Hi Dogan, Dogan Culum said: For loadcell I am using 10kg with 2mv/V and supply voltage is 10V. So I have 20mV for 10kg. My resolution must be 0.1gr. So 20mV / 100000 = 200nV. For 800.0 gr my maximum input to INA188 will be around 1.6mV. I will be using…
