Laser Driver 3-CH 16-Pin QSOP

The MAX9483 high-performance, multimode, laser-diode drivers (LDDs) are designed for CD and DVD combination pickup heads. The drivers consist of three input channels, an RF oscillator, and two precision current-amplifier outputs to drive the CD and DVD laser diodes. The MAX9483 support multiple CD and DVD read/write standards, such as CD-R/RW, DVD-R, DVD+R, DVD-RW, DVD+RW, and DVD-RAM by choosing the writing control signals and input currents on these input channels. The peak total output current is 400mA with a current gain of 100 at each channel. External resistors set the oscillation frequency and output swing. The MAX9483 is offered in 16-pin QSOP and 4mm x 4mm 16-pin thin QFN packages. Both devices are specified for 4.5V to 5.5V supply and 0°C to +70°C temperature range.
