Other Parts Discussed in Thread: OPA1622
Hi there !
I have a question regarding paralleling two INA1620 amplifiers according to sboa352 article.
I want to connect the output of LPF based on the Figure 40 of AK4490 datasheet with paralleled INA1620 amp.
Could you please tell me which INA1620 input should the output from LPF be connected to? If it goes to one of the inputs (inverting or noninverting), then what should be done with the other input left?
