4 Summary

From the test cases conducted in this application note, the TAX5XXX audio devices which are designed without a PGA, is able to record or capture sound of any microphones due to the high dynamic range and when amplification is needed, the digital gain can be applied through digital volume (DVOL) without degradation.
