DRV800 8-channel digital laser driver
Koheron DRV800 is a 8-channel laser driver with digital control. DRV800 can drive floating and cathode-grounded laser diodes. It delivers up to 210 mA per channel with up to 6.5 V compliance voltage. Channels are parallelable for higher output current. Each channel has a dedicated DC to 7 MHz modulation input. Typical applications include photonic integrated circuits control, and laser diodes aging and testing.
