Current noise
The DRV10 laser diode driver current noise was measured across a 5 Ω resistor with a supply voltage of 5 V.
Integrated noise in the 10 Hz - 1.1 MHz bandwidth is 158 nArms at 100 mA current and 159 nArms at 200 mA current. The DRV10 laser diode driver was supplied from a DC/DC converter. The peak of the current noise at 1 MHz is caused by the laser diode driver itself and will not be reduced by using a quieter power supply.
