3ch Laser Diode Driver
I
GENERAL DESCRIPTION
I
PACKAGE OUTLINE
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.
