MAX9483/MAX9484 are high performance, multi-mode laser diode drivers (LDDs) designed for CD and DVD combo pick-up heads. The driver features three input channels, an RF oscillator, and two precision current amplifier outputs for driving CD and DVD lasers. By selecting the write control signal and input currents on the input channels, the MAX9483/MAX9484 can support multiple CD and DVD read/write standards such as CD-R/RW, DVD-R, DVD+R, DVD-RW, DVD+RW, and DVD-RAM. Peak total output current is 400mA and each channel has a current gain of 100. Oscillator frequency and output amplitude are set using external resistors. The MAX9484 also adds an external resistor pin that allows the oscillation frequency of the two outputs to be set independently. In addition, the MAX9484 is capable of accepting a write control signal in either low voltage differential signaling (LVDS) mode or single-ended mode for reliable high-speed write operations.
