Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX9483/MAX9484 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/MAX9484 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 MAX9484 features an extra resistor input allowing the oscillation frequencies of the two outputs to be set separately. Additionally, the MAX9484 allows the writing control signals to be received in low-voltage differential signal (LVDS) mode or single-ended mode to provide reliable high-speed writing.

The MAX9483 is offered in 16-pin QSOP and 4mm x 4mm 16-pin thin QFN packages. The MAX9484 is offered in a 4mm x 4mm 20-pin thin QFN package. Both devices are specified for 4.5V to 5.5V supply and 0°C to +70°C temperature range.
