Laser Driver for Projectors
MAX3600
10
Detailed Description
The laser driver for projectors supports video imaging
with red, blue, and green lasers. Each output includes
a 10-bit video DAC with programmable gain and offset.
OUTPUT1, OUTPUT2, and OUTPUT3 support opera-
tion with red, green, and blue lasers. OUTPUT4 and
the PRBS generator provide noise as required for cer-
tain synthetic green lasers. The MAX3600R (Figure 3),
MAX3600G (Figure 4), and MAX3600B (Figure 5) are
monochrome laser drivers.
