Could you please let me know the power consumption of the AD734.
I can only find the quiescent current and the operating supply range on page2
of the datasheet and the internal power dissipation on page3.
Could you give me the range of the typical current for work or tell me the
range of input current and the efficiency of the AD734.


the power is dissipated mainly by the quiescent power and the drive power.
We have express this as  Figure 1
where Vs is (+Vs - -Vs)
So for the AD734 PD = (30V * 12mA) + (15V * 10V/10k) - 10V^2/10k assuming 15V
supplies and a 10k load is 365mW.
