MAX3600 General Description The MAX3600 laser driver for projectors supports video imaging with red, blue, and green lasers. Each output includes a 10-bit video digital-to-analog converter (DAC) with programmable gain and offset. For operation with synthetic green lasers, the driver includes a periodic off function and a fourth output with a random-noise generator.
