Product Number: ADAU1787
Hello!
I need a help to review schematics implementation converting analog microphone differential output to ADC single ended input on ADAU1787.
Here are details:
- the microphone used Infineon analog IM73A135V01XTSA1 microphone with diff. output;
- the microphone powered from 1.8V;
- I want to connect this microphone to single ended ADC input on ADAU1787 device;
- To support full dynamic range I want to use external OPAMP circuits powered from 1.8V as well;
- The part OPA1671 part selected - see circuit shown.
Is any concerns about this circuit?
Thank you!
