The input of the A-112 is already DC coupled. For DC coupling of the output
one has to short the 100nF capacitor C11. From the schematics I'd expect a
negative DC offset of about -2.5V and an inverted output as the current
output of the DAC is converted into a voltage by an opamp inverter without
input resistor. You will have to add another inverter (e.g. A-175 or A-138c)
to obtain a non-inverted signal and a positive (or with A-138c adjustable)
offset.
