Other Parts Discussed in Thread: OPA2353, OPA337, OPA2134, OPA1622
I have several questions about PCM1681.
Please refer to the datasheet, figure 26 and figure 33 show the recommended active filter circuits, my question is:
(1): can both filter circuits be used as active filter circuit? Which one is the priority?
(2): For the circuit with OPA2353, if all of the VOUT1 to VOUT7 are used, can I connect all of the non-inverting input of operational amplifier to the output of OPA337? Or is this a must?
(3): For the circuit with OPA2134, if I only connect the positive power supply, can the active filter circuit work?
