Current precision of ADN2830

Hi,

I have 2 questions regarding ADN2830, TEC Controller IC.

1. What is the current (or power) precision of the output power of the ADN2830? Like how precisely it can be varied (like 1microAmps/10microAmps).

2. Is it possible to control the PSET pin with a voltage source(using a precision DAC) instead of a resistor ?

Kindly answer these questions ASAP.

Thanks in Advance.

Regards,
