Part Number: PCM2906C Other Parts Discussed in Thread: HID2 I'm using the evaluation board (SBAU-195) as a patern for designing a USB audio interface.
Why are HID0, HID1, HID2 pulled up to logic high when internally they are pulled to ground? Why not…
Part Number: PCM2906C How much ENOB degradation would result in using the internal VCCI. Our SNR requirement is 40 dB relative 50 mV. We calculate a ENOB of 7 or greater is needed. Since the PCM2906 is a 16 delta-sigma adc, would the variation in VCCCI…
Part Number: PCM2906C Dear Support,
I have finished my design with PCM2906C. It works properly, but I needed to have Microphone input instead of line-in. I have designed proper buffer to drive electret microphones and everything works properly.
Nevertheless…
Part Number: PCM2906C Other Parts Discussed in Thread: DIR9001 , SRC4392 Tool/software: Is it possible to get an analogue output from a S/PDIF input? From the diagram it isn’t obvious whether it is possible to route the signal that way.
Part Number: PCM2906C
Tool/software:
Hi,
Could you please clarify why the USB differential interfaces (D+ and D-) are necessary for data transmission to the chip? Is it not possible to connect directly to the DAC or ADC inputs/outputs? Does this…
Part Number: PCM2906C Other Parts Discussed in Thread: TUSB4041I , Tool/software: Hi TI team members,
Im designing an USB Audio Card with multiple Input/ouput channels ( 8 mono inputs and 8 mono outputs, with Analog and Digital SPDIF I/F).
Checking…
Part Number: PCM2906C Hi,
Our customer designed the circuit shown in the diagram below, fabricated a prototype board, and evaluated it. When operated by applying 5V from the PC (USB), the PCM2906C generates abnormal heat. (Although I have not specifically…
Part Number: PCM2906C Hi,
The datasheet states that the analog performance of the ADC may be degraded when using an internal voltage regulator.
It seems that the internal voltage regulator turns off when power is supplied externally to the VCCCI…
