Single programming resistor Rp provides an output-current range of about six decades.-Note that this resistor`s TC is also a potential source of error; it dissipates 125 mW when JliN ~ 5 V. The maximum deviation is typically 50 nA or 0.0002% of full scale.

This voltage-controlled current source uses optocoupler IC2 to eliminate an error found in more conventional circuits and which is caused by the output transistor"s base current.
