Audio Codec with USB interface and Linux driver support?

Other Parts Discussed in Thread: TLV320AIC3109-Q1, TLV320AIC3104-Q1

Hello all,

I am looking for an industrial temp. range single or dual audio codec with USB and Linux driver support. Performance requirements are rather minimal (8 or 16 Ksps, 16-bit resolution, differential microphone interface with PGA, line output). Obviously there is not a single-chip solution for this purpose but I hope there is at least a simple (but proven) MCU + Codec combination that fullfils my requirements. Robust Linux support is the most important parameter. A similar (although overspecified for my purpose) device on Analog Device's portfolio is SSM2604.

Is there anything in TI's portfolio that fullfills these requirements?

Thank you in advance

    Hi, Dimitrios,

    From the codec point of view, it seems you need a simple device capable of meeting the mentioned temperature range. Maybe you can take a look to the TLV320AIC3104-Q1 stereo, or TLV320AIC3109-Q1 mono, audio codecs. These devices are qualified for automotive temperature ratings which goes from –40°C to 85°C and –40°C to 105°C respectively.

    Currently we are no supporting Linux driver integration for our audio codecs, we have a couple drivers that could be used as reference for these parts, please take a look to this e2e wiki.

    I would recommend you to ask my colleagues on the Microcontrollers forum for the best MCU recommendation for your application.

    Best Regards,
