NJW4702 - 3ch Laser Diode Driver

General 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.

NJW4702 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. www.DataSheet4U.com 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 Current 250mA typ. q Bi-CMOS Technology q Package Outline PCSP16(3.5mm 0.
