I want to build a DAC with CS8414 and AD1853,
but i don't know how many PF C52* and C53*
(remarked in the picture below) should be .
Can some one tell me?
I want to use OPA2604 instead of OP275.
Thanks!!!!
Some operational amplifiers don`t like ultrasound signals on input. This capacitors is simply filter for it. Value may be 100-4700 pF range. Use high speed opamp, then this capacitors not needed. Looks like AD812.
I've made DAC on AD1853 (PCM2702-DIR1703-AD1896-AD1853) with the same output stage suggested by Analog. I used OPA627 for I/V and AD797 for filter with great results.
