Other Parts Discussed in Thread: AM5718, PCM5122

HI TI

We a test system for mic sensitivity。we need play 1khz sing by speaker，

do you have some analog ic solution？we would like to have linux driver for chipset. CPU is am571x

suspect:

CPU->AUDIO ADC(i2s)->AMP->filter->speaket

or CPU->DAC（1k sine wave）->AMP->filter->speaker

thanks

Are you looking for an AM571x EVM that supports audio solution? I don't think the TI EVMs support and audio solution. However, there are 3rd part EVMs that support audio (like BeagleBone). Also - the Jacinto6 EVM(s) which are automotive version of the same processor supports AIC3106 codec.

Hi Rober

Not for AM571x EVM, we have a project with AM5718，We will make a new layout for design。

We found PCM5122 on TI Website with a Linux driver could we use it in AM5718?

Linux Drive:https://www.ti.com/tool/PCM512XSW-LINUX

Does Ti have more DAC solutions?(Ti reference design or 3rd part).

AIC3106 is Audio CODEC ，WIth MIC input and SPK output ，We just need an AUDIO ADC(Speaker output only) ......

Thanks

The AM5718 McASP interface is very flexible, and can be programmed to work with a wide variety of audio components. Yes - AM5718 will work with PCM5122 (I2S-based interface), using I2C or SPI for configuration.
