I use AD8333 in evaluation boards from analog devices. There is used like
current-to-voltage (I-V) converter the AD8021 with single output. I want to use
some current to voltage converter with differential output. Is possible use
AD8139? How can i connect differential input of AD8139 to single output of


When interfacing one of our differential amplifiers to a current o/p, we
recommend that you first convert the o/p current into a voltage ( within the
o/p compliance range) .
This technique is used in lieu of direct I/V conversion to prevent fast slewing
currents from overloading the amplifier and introducing distortion.
Refer to the AD8139 datasheet for circuit configuration for singel ended to
differential conversion circuits.
