    TI Thinks Resolved
    Part Number: OPA547 Other Parts Discussed in Thread: OPA593 , OPA192 , OPA182 , OPA189 , TLV3501 Hello TI Support Team I need to derive a bidirectional constant Current Source up to +/-200ma, can i use the OPA547 using the Figure 14 with +/-15V Supply and…

  • RE: OPA189: Improper step response of OPA189 based low side noninverting photo diode amplifier

    I do think the distortion of the square waveform has to do with OPA189 chopper amplifier trying to auto-correct a large input offset voltage after it was induced by the output being pushed against its negative supply. To confirm, please use instead a…

  • RE: Should noise bandwidth be equal to signal bandwidth in noise calculation?

    Resolved
    Hi Marek, Thanks for your detailed reply. So high GBW is not always better right? If my signal bandwidth is 10kHz, it would be better to use a lower GBW opamp (OPA182, for example) instead of OPA627?

  • OPA388: OPA388 close loop gain

    Part Number: OPA388 Other Parts Discussed in Thread: OPA2182 , OPA182 Dear team, Customer has a requirement, I recommend OPA388 but customer think the close loop gain @ G=100 is small. So do we have similar zero-cross, zero-drift amplifier but with higher…
