Default dac output stage

hi all, wondering if someone could help me understand this circuit.

if you download the link, and scroll right to the bottom, its the one with a few opamps,

http://www.datasheetarchive.com/data.../88/88703.html

I can see there is an I-V convertor, and a buffer, what does the bit in the middle do please,

is this typcial output stage for current output dacs?

thanks
