AS3341D

AS3341 is a voltage controlled current source with internal temperature compensation and a matched pair of NPN transistors. Current source uses a temperature-compensated core of the VCO AS3340, with an exponential and linear control scale. The output current Iout- can be varied within a wide range from 50 nA to 500 uA. AS3341 also has a current output Iout + = 1 / 4Iout- which can be used to compensate for the linearity of the control characteristic for a large output current Iout-.
