  • 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…

  • RE: OPA357: OPA357 Output Multiplexing using shutdown function

    Resolved
    Hi Mike, Thank you for quick reply. OPA837 input range is +-1V, so I will have to rescale my input. But its good that it allows multiplexing. Thank you for help. Regards, Vishal
