Manu said:Hi cviller,
Did you build the D1?
I only built the I/V stage and connected it to a pcm1798. I haven't had time to redo it with a better dac, but that is on my list and I plan to try to use jfets instead of irf610.
Tazzz said:Does anybody know the actual transconductance of an irf610 at 10mA ?
About .1S or so. This is the equivalent of about 10 ohms.

Thanks!
What would you think of scaling the positive rail and the I/V resistor for some 15-20volts and drive a F4 directly ?
Possible slewrate problems ?
IRF610 Alternative?
Hi Guys,
I'm currently building a DAC and would like to try the D1.. but it seems i cant find the IRF610 locally unless i order them online.. Im hoping i can use alternatives.. Which to do you will be best the substitute:
IRF530
IRF640
IRF740
IRF830
IRF840
thanks

Try to obtain som FETs from Fairchild Semi :

in fact- you're safe
I'll loose Naah on Manu ; frenchies are responsible for Rossi's drek tires
seems that they're slept on laurels.......
