  • OPA4348: Substitute with hight EMIRR

    TI Thinks Resolved
    Part Number: OPA4348 Other Parts Discussed in Thread: TLV9004 , OPA4391 Tool/software: I need to replace OPA4348 with op amp that has better irradiated immunity. I see that some op amps are classified as EMI Hardened. Maintaining the same characteristics…

  • OPA4348-Q1: Voltage Buffer output to ADC has spikes

    Part Number: OPA4348-Q1 Tool/software: I am using OPA4348AQPWRQ1 as a voltage buffer to a STM32 ADC pin. I need to convert input voltage of +30V to -30V to a 0-3.3V level and hence used a resistor divider network. I am getting these intermittent…
