STEVAL-CCA023V1:Demonstration board for low noise microphone preamplifier with 2 V bias based on the TS472

The STEVAL-CCA023V1 demonstration board is designed as an evaluation platform for the TS472 low noise microphone preamplifier with 2.0 V bias and active low standby mode.

The board supports customization of the testing conditions, allowing the gain of the TS472 device to be adjusted, or an electret microphone to be biased either externally or using the TS472 builtin 2.0 V bias voltage.
