Koheron DRV110 is a current source that can drive up to 1200 mA of current with a compliance voltage of 12 V. Its current noise of 300 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).

Current noise

The power spectral density of the DRV110 current noise was characterized using a 2.5 Ω load and followed by an instrumentation amplifier. Both drivers were supplied with 9 V.

DRV110 current noise

Current noise integrated between 10 Hz and 1 MHz is 236 nA for the 750 mA version and 372 nA RMS for the 1200 mA version.
