TLV320AIC12: About device operation

Part Number: TLV320AIC12
Other Parts Discussed in Thread: TAC5212

Hi team,

I would like to achieve the following
Since G.711 is used, I want to input and output 8kHz sample data.
However, if the 8kHz sample is left as it is at output, quantization noise will increase, so I would like the codec to convert the sample rate from 8kHz to 32kHz or 48kHz, and perform the processing until the FIR filter is applied.
(Conversely, the microphone recording side should be capable of decimation.)
Set I2S to 8kHz sample data communication setting, upsample/interpolation/FIR in DAC
ADC side should be downsampled/decimated.
(Monaural specification is fine.)

I thought the TLV320AIC12/13/14/15 series would be good, but are there any other devices you would recommend?
Also, I will be using 8 ohm speakers.
I would like to have an output power of about 1W, but this device is listed as Max output power 190mW (AIC12/13/12K OUTP2/OUTP3). Is this the power limit?

Sincerely,
Ryu
