NJW4710
4ch Laser Diode Driver for Blue Laser Diode
sGENERAL 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
