Problem with PCM2702e
Hi.
i've just build a usb-dac using pcm2702e and am having problems connecting it to the pc. the first time i done it it was found and then the chip over heated. the second time (new chip) it flashed as unknown device. i have checked the voltages on the pins, 3.3 and 5v and all are correct. im using 2937et-3.3 for 3.3v regulator and lm7805 for the 5v regulator. i will upload a schematic and eagle layout soon. has anyone had a similar problem and it so, how was it fixed? cheers |
