PCM290(2/6) Help please.
I need some help. I am trying to build a usb audio adc/dac using the pcm2906 from TI using the pcm2902's evaluation board. I created a list of parts needed, but need some tips.
Resisters 4x 1.5k? RA001(3) R001 2x 22? R002 R003 1x Jumper R004 1x 1M? R005 1x 22k? R006 9x 12k? R007 R101 R102 R105 R106 R111 R112 R115 R116 4x 3.9k? R103 R104 R113 R114 4x 100? R107 R108 R109 R110 Caps 1x .1µf C001 7x 1.0µf C002 C003 C004 C005 C006 C007 C008 2x 18pf C009 C010 7x 10µf/16v C101 C102 C107 C108 C109 C114 C115 4x 1800pf C103 C104 C112 C113 4x 330pf C105 C106 C110 C111 The above are the resisters and caps needed for the board, with their corresponding part number on the evalutation board. I need some tips though. Which type of resisters should I use? Metal, Carbon, etc? And which types of capacitors? Tantalum, Ceramic, Electrolyte, etc? I am using the reg104fa-a instead of the reg103ga-a if it makes any difference.
