I'm looking for a sigma delta 3.5 digit display-type A/D converter with display hold and on-chip LED drivers. Something like the MAX1496EPI seems nearly ideal, but I can't find a vendor for it, and am hesitant to commit to a part which may not be available in small quantities later. The alternative, I suppose, is to use a dual-slope converter like the ICL7135, and just bite the bullet as regards board real estate and other problems.
