I don't think this part would be very useful for other than the intended use. At best one might get a kind of low power lab supply (20 V up to 1 A at lower voltage ?). Maybe a little like a low end, limited range 5.5 digit source meter with an extra sense input (a kind of 3 wire mode).
The SW may be limited in control.
I won't expect really high end components. At least one would not need them for the specs. Likely CMOS OPs and SD-ADC chip (e.g. LTC2400).
