Koheron DRV110 is a current source that can drive up to 1200 mA of current with a compliance voltage of 15 V. Its current noise of 400 pA/√Hz (200 pA/√Hz for the 750 mA version) is below the noise of a 1 A Poissonian current source. The DRV110 can be used to drive high current LEDs below the shot noise limit. Thanks to its high compliance voltage and its low noise performance, the DRV110 is an excellent choice to drive quantum cascade lasers (QCL).
