Datasheet

7.7. Analog Audio Input Port

The ALC5616 has two types analog input ports: microphone input and line input.

 IN1P

The IN1P is a microphone type input port. The input port is single-ended type input. The microphone

input port has its microphone bias and microphone boost. The low noise microphone bias can improve

recording performance and enhance recording quality. Build-in short current detection scheme can be

used for switch detection. Multi-steps microphone boost gain set by sel_bst1 (MX-0D[15:12]) is easy

to use for microphone application. Pow_bst1 can be used to power down the MIC1 boost and

pow_micbias1 can be used to power down the microphone bias 1.

 IN2P/N

The IN2P/N is a dual type input port: microphone input and line input. Microphone input can be

configured to differential input or single-ended input by MX-0D[6]. Multi-steps microphone boost

gain set by sel_bst2 (MX-0D[11:8]) is easy to use for microphone application. Pow_bst2 can be used

to power down the MIC2 boost. As line input, it has volume control for tuning by MX-0F[12:8] and

MX-0F[4:0].
