TLV320AIC3109-Q1: Query

Part Number: TLV320AIC3109-Q1


Tool/software:

Hello Team,

Currently we are using TLV320AIC3109-Q1 Audio codec in our design.

As per requirements, instead of going with internal Mic Bias of TLV320AIC3109-Q1, we are planning to use External Mic Bias voltage of 5V from an external Low Noise LDO.

As per Data sheet recommendation, Internal MIC Bias is of 2V/2.5V/AVDD (3.3V) voltage level.

Query

1.is there any impact in using 5V external bias Voltage instead of 2V/2.5V/AVDD level.

Note:

1.While using External Mic Bias option, internal Mic bias pin will be kept open.
