7.3.5 Audio Analog Inputs

The TLV320AIC3109-Q1 includes two single-ended audio inputs. These pins connect through series resistors and switches to the virtual ground pins of two fully differential operational amplifiers. By selecting to turn on only one set of switches per operational amplifier at a time, the inputs can be multiplexed effectively to the PGA.

By selecting to turn on multiple sets of switches per operational amplifier at a time, mixing can also be achieved. Mixing of multiple inputs can easily lead to PGA outputs that exceed the range of the internal operational amplifiers, resulting in saturation and clipping of the mixed output signal. Whenever mixing is being implemented, take adequate precautions to avoid such saturation from occurring. In general, the mixed signal should not exceed 2 VPP (single-ended).

In most mixing applications, there is also a general need to adjust the levels of the individual signals being mixed. For example, if a soft signal and a large signal are to be mixed and played together, the soft signal generally should be amplified to a level comparable to the large signal before mixing. In order to accommodate this need, the TLV320AIC3109-Q1 includes input level controls on each of the individual inputs before being mixed or multiplexed into the ADC PGA, with gain programmable from 0 dB to –12 dB in 1.5-dB steps. This input level control is not intended to be a volume control, but instead used occasionally for level setting. Soft-stepping of the input level control settings is implemented in this device, with the speed and functionality following the settings used by the ADC PGA for soft-stepping.

Figure 20 shows the single-ended mixing configuration for the PGA, which enables mixing of the signals LINE1L and LINE1R. The PGA MIX is similar, enabling mixing of the LINE1R and LINE1L signals.
