NJW4710 www.DataSheet4U.com 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 sFEATURE q Operating Voltage q Internal Oscillator Circuit q Rise Time / Fall Time q Maximum Output Current q Bi-CMOS Technology q Package Outline sPIN CONFIGURATION sPACKAGE OUTLINE NJW4710VE1 Vcc1=4.5V to 5.5V, Vcc2=8.0 to 10.0V 200MHz to 500MHz 0.8ns typ. 250mA typ.
