  • OPA625 input offset

    Resolved
    Other Parts Discussed in Thread: OPA625 Hello, I'm trying to use OPA625 in a current meter design. At first stage, the input signal is passed through a voltage follower to lower the output impedance. Here is a circuit: According to the datasheet,…

  • OPA837: common-mode input range violation

    Resolved
    Part Number: OPA837 Other Parts Discussed in Thread: OPA625 , TIDA-01055 I was wondering about the common-mode input range of the OPA837 when used as a reference buffer for an ADC. The TIDA-01055 compares the OPA625 with the OPA837 as a lower power option…

  • PGA281: PGA281 input noise due to protection R - PGA281 output driving capability

    Resolved
    Part Number: PGA281 Other Parts Discussed in Thread: ADS9110 , THS4551 , OPA625 Hello Team, would 15k resistors on both inputs of the PGA281 influence the noise performance? Typically chopping input does not interface good with high impedance source but…

  • PGA281: Is the PGA281 differential output capable of driving a SAR ADC directly ?

    TI Thinks Resolved
    Part Number: PGA281 Other Parts Discussed in Thread: ADS9110 , OPA2320 , THS4551 , OPA2625 , ADS8900B , OPA625 Is there a limitation of drivin SAR ADC directely ( kickback, settling , accuracy ). In my understanding, a ADC-driver needs higher BW to handle…

  • RE: OPA2626: Settling Time in small signal space

    So I went ahead and looked at the settling plot in the OPA2626, this is almost certainly a slew limited settling time, would be much faster if the input edge was slowed to stay out of slew limiting. Little history, This is a dual, non-power control, version…

  • RE: OPA2192: Request for additional information regarding THD+N for OPA2192 and OPA2141

    Resolved
    Hi Shane, have you thought about using the OPA837 or OPA625? These OPAmps have very low distortion specs at 100kHz. By the way, intermodulation can be identified by the appearance of sum and difference frequencies. Kai
