Hi,

I found that my PWM DAC is too noisy, so I'm trying to make an R-2R DAC
(8-bit).  I'd like to use one of the thin-film integrated parts (like
what Bourns or BI-Tech makes) but all the distributors I check show no-
stock.

Anyone know of part suitable for R-2R use that's readily available?

Thanks.
H.

I'd try and find out why it was noisy

Well...it's noisy because it's PWM!  Without a lot of filtering, one
will usually get 5-10 mV of noise.
