Other Parts Discussed in Thread: TLV320AIC3106
Hi TI Experts,
We are planning to connect TLV320AIC3106 (CODEC) to the audio amplifier (TPA3139D2). The analogue output from CODEC (on the pin LEFT_LOP) is connected to the audio amplifier as single ended. We are setting up the gain of CODEC channel at 0dB (synthetic gain). The gain of the TPA3139D2 is fixed at 20dB. But our required gain at the output of the audio amplifier is 16dB. I am attaching the reference schematic picture below, My question is,
- How to reduce the gain at the input of audio amplifier to -4dB without compromising any audio performances to adjust the audio amplifier output gain to the required level16dB?
- What are the methods or techniques used for reducing the gain at the input?
Best Regards
Sharvy
