Special Purpose Amplifiers Procurement Notes

Verify the specific suffix 'TR' against the target part number, as it indicates tape-and-reel packaging which differs from tube packaging. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) requirements for the assembly process. Ensure the 16-QFN package footprint matches the design layout. Check for any obsolescence notices or lifecycle changes from the manufacturer before finalizing procurement plans.

Special Purpose Amplifiers Selection Notes

Select this component when designing systems requiring 1.25 Gbps data rate support with low power consumption. The 42 dB gain and 750 MHz bandwidth are suitable for restoring degraded optical signals in passive optical networks. Consider the 3.3 V nominal supply requirement and the thermal characteristics of the QFN-16 package for heat dissipation in dense PCB layouts.
