MICBIAS is a low noise microphone-bias-voltage generator that provides 1.65V highly regulated output. The output voltage can be programmed with 6 trimming Bits for ?+/-75mV range. The bias-voltage generator has low output noise of 3.5uVRMS across the audio range frequency. It has typical PSRR of 80dB across audio range.
The external mode operation gives option to bypass the MICBIAS output to provide with customized bias-voltage.
