Overview
The ADN2526ACPZ-R7 is a high-performance laser diode driver designed by Analog Devices Inc. for direct modulation of packaged laser diodes. This device is particularly suited for applications requiring high-speed data transmission, such as in fiber optic communication systems. The ADN2526 features active back-termination, which helps in absorbing signal reflections from the TOSA (Transmitter Optical Subassembly) end of the output transmission lines, thereby enhancing optical eye quality even in cases of significant mistermination. It is compliant with the SFP+ MSA (Multi-Source Agreement) and is packaged in a compact 3 mm x 3 mm LFCSP (Lead Frame Chip Scale Package), making it ideal for space-constrained modules.
