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 to 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.
