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.
CLK
The MAX3600B/R/G are monochrome drivers for blue,
red, and green lasers. The MAX3600A guarantees
higher full-scale output currents than the MAX3600, and
is recommended for new designs.
