ADC3101 Control Software

Figure 8. Clocks / Interface Panel

4.1.3 Analog Settings

The TLV320ADC3101 software allows access to two analog panels:

1. Audio Inputs – This panel allows the user to access the Input Routing and Input Volume Control tabs

shown in Figure 9.

2. Automatic Gain Control (AGC) – This panel allows the user to configure the AGC. Note that the

TLV320ADC3101 supports the left and right channel AGCs, which are identical. The software supports

the left AGC only. See Figure 11.

Before changing a control, see the data sheet to ensure that a particular control is compatible with the

current state of the device. As an example, some controls in the analog settings panels must be modified

in a particular order as described in the data sheet.

4.1.3.1 Analog Audio Inputs

The Input Routing tab allows selection of all available single-ended and differential inputs including any

gain associated with the input. Also available are PGA bypass controls, unused inputs biasing, and ADC

volume stepping.
