ADC/DAC or CODEC for guitar effects pedal

Other Parts Discussed in Thread: PCM3002

Hi All,

Does anyone have any suggestions for a ADC/DAC pair or a codec which could be used for the input and output of a guitar effects pedal/stompbox?

Regards

    Hi, George,

    We could provide some suggestions for audio devices that could be suitable for this application, but first we need more information about the general system level requirements like like ADC/DAC performance, number of channels, processing, power requirements, etc.

    Hi Diego,

    Only needs to be 1 channel in and 1 out, at least 48kHz samplin,  processing will be done elsewhere, ideally i2s interface.

    Its mostly is there a chip with the "universal front end" as with the pcm186* but with a line level analogue output also.

    Many thanks

    Hi, George,

    Thanks for the feedback. Depending on the complexity of your design, we have a couple options for you. If you need a simple device able to convert from analog to I²S and receive I²S data to stream analog output, probably a device like PCM3002 could be considered. A more complex solution, with better performance could be achieved by using an ADC/DAC combination between a PCM186x and PCM51xx devices.
