Characterization

Current noise

The figure below shows the current noise of the DRV200S laser driver. The setpoint is produced by a VREF100 voltage source.

DRV200S-A-200 (200 mA) modulation response
DRV200S-A-400 Low noise laser driver with external setpoint modulation response
DRV200S-A-400 (400 mA) modulation response

Modulation performance are characterized using a DFB laser operated at 80 mA. The gain high modulation (H) is measured at 200 mVpp and the gains medium (M) and low (L) are measured at 2 Vpp. Gains are normalized to the medium modulation gain at DC.
