Limiting amplifier for optical receiver front-ends
The Maxim Integrated MAX3645ESE-TG035 is a limiting amplifier designed for use as a data quantizer in optical receiver systems. Its core job is to take a small, variable-amplitude input signal from a photodiode transimpedance amplifier and output a clean, logic-level signal with fixed swing, regardless of the input amplitude. This makes it a key building block in fiber-optic communication links, particularly at the receiver end where signal integrity matters.
Package and mounting – 16-SOIC footprint
If you are replacing a MAX3645ESE on an existing board, the TG035 suffix indicates a tape-and-reel packing variant, but the package itself is identical.
Lifecycle – still in active production
This is a straightforward, available part for optical receiver applications.
