Develop an hardware USB audio ADC

Hi !

We are looking for someone to develop a USB 2.0 FS Audio Class 1.0 device, fully compatible with Windows, Android and iOS.

- 1 Analog Mic Input @ 96kHz/16bits

- If possible, 1 to 3 GPIOs

- If possible, 1 Analog Output, lower resolution is ok

- USB 2.0 Full Speed, Audio Class 1.0, asynchronous mode

- Powered by USB / 50 mA max for ADC and controller.

- Programmable USB product string (iProduct) and serial number (iSerialNumber)

- Target Size : 35x35mm

- Electronic part targeted price : under 12$ @ 1000pces

- Delay : 1month for a working prototype/ demoboard

The device is to be used for timing measurement purposes. The sampling frequency’s stability and precision are essentials. Therefore, the ADC clock will have to be generated by a TCXO and a real asynchronous mode (in terms of the USB Audio Class 1.0) communication must be established over USB.

So, in the case of a microcontroller and a separate serial ADC, the ADC would have to be the master of the I2S communication, in order to guaranty the sample rate.

Have a nice day !
