PCM1860-Q1: analog input numbers

Part Number: PCM1860-Q1

Hi Sirs,

I need 8x single end analog audio input, the sampling rate is 16k with 16bit and 1x I2S output. The 8x inputs will work at the same time. so which part of the PCM186x_Q1 can meet my requirement? and what's the sampling rate of the output?

Thanks

Hello,

We currently do not have an 8-channel simultaneous sampling audio ADC in our portfolio.

However, you can daisy chain two of our TLV320ADCx140 devices to create an 8x mic input capture system which outputs all 8 on I2S or TDM output options.

The sampling rate will be 16kHz if you set the part up that way and all 8 channels will be sampled and transmitted at 16kHz.

Here's a good app note with more information:
