Part Number Status
MAX3601 Active: In Production. See Ordering Information for details.


The MAX3601 laser driver for pico projectors supports video imaging with red, blue, and green lasers. Each output includes two 8-bit digital-to-analog converters (DAC) with programmable gain and up to 400mA driving capability per channel. DAC A has a full-scale current up to 320mA while DAC B has full-scale current up to 80mA. All three channels can be combined into a single channel with up to 1.2A drive capability.

Maxim’s patented technology allows pulsed current to operate lasers efficiently while reducing speckle. This feature operates from the video data clock. The driver is available in a 3.0mm x 3.5mm, 42-bump wafer-level Package for commercial applications, and a 5mm x 5mm, 40-pin TQFN package for industrial and automotive applications.
