Manufacturer's part number :


Manufacturer New Japan Radio

New Japan Radio

Description :

NJW4710 is a laser diode driver for the operation of a grounded blue laser diode. It is suited to drive a blue laser diode, because it is operated by split power supply. It includes 4 channels current amplifiers for 4 different optical power levels. An on-chip RF oscillator is provided to reduce laser mode noise during read mode. Oscillation frequency and oscillation amplitude are defined by two external resistors.
