NJW4702 Datasheet (New Japan Radio) - 3ch Laser Diode Driver

NJW4702, 3ch Laser Diode Driver

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.
