It delivers up to 100 mA bias current and 85 mA modulation current from a 2.97V to 3.63V supply, drawing 47 mA supply current. The 24-TQFN (4x4 mm) package with exposed pad provides a low-inductance thermal path to the PCB ground plane, critical for maintaining eye-diagram margin at 622 Mbps. ## Supply rails and package integration The 2.97V to 3.63V supply range allows the driver to run from a standard 3.3V rail with margin for ripple and load transients. Tape & Reel packaging (also available as Cut Tape) suits automated pick-and-place assembly for volume production.","metaTitle":"MAX3646ETG+T Analog Devices Laser Diode Driver, 622Mbps","metaDescription":"MAX3646ETG+T laser diode driver from Analog Devices, 622Mbps data rate, 100 mA bias, 85 mA modulation, 24-TQFN, active production.
