If it is fast enough (GBW, slew) then it is not accurate enough (Vis, Vcm); if accurate enough then wrong supply range; if right supply range then wrong common mode input range; if good common mode input range then wrong output range, etc ad nauseam. Even with '... never needing more than 640K ...'in mind, it will be a long time until analog PGAs are as useful and ubiquitous as digital FPGAs." 收起
