3ch Laser Diode Driver sGENERAL DESCRIPTION NJW4702 is a laser diode driver for the operation of a grounded laser diode for CD-R and CD-RW drivers. It includes three channels current amplifiers for three different optical power levels. Reference inputs are voltage input, and voltage control is possible without external resistors. 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. .. sPACKAGE OUTLINE NJW4702SE8 sFeatures q Operating Voltage 4.5V to 5.5V q On-chip RF Oscillator 200MHz to 500MHz q Rise-time/Fall-time 1.0ns typ. q Maximum Output...
