It integrates the bias and modulation current paths for driving a laser diode in SFP, SFP+, and parallel optical modules. The bias current is set at 15 mA and the modulation current at 15 mA — these two parameters directly control the laser's optical output power and extinction ratio. The 55 mA total supply current at 3.3 V means the driver's own dissipation stays under 200 mW, which matters for thermal management inside a sealed transceiver housing. ## 24-TQFN exposed-pad package Housed in a 24-lead WFQFN with an exposed pad (4x4 mm body per the supplier device package designation 24-TQFN). The 0.5 mm pitch QFN footprint is routable on a standard 4-layer FR4 board.","metaTitle":"MAX3740AETG+T Laser Diode Driver, 3.2 Gbps, 24-TQFN","metaDescription":"Analog Devices MAX3740AETG+T laser diode driver, 3.2 Gbps data rate, 15 mA bias/modulation, 2.97-3.63 V supply, -40 to +85 °C, 24-TQFN.
