The Maxim Integrated MAX4036EXK+T is a single-channel general-purpose op-amp in a 5-pin SC-70-5 package. Its headline numbers are a 4 kHz gain-bandwidth product and a 900 nA supply current, with rail-to-rail output swing across a 1.4 V to 3.6 V supply range. This combination targets battery-powered sensor interfaces, portable instrumentation, and always-on signal conditioning where every microamp of quiescent current matters.
The 900 nA supply current is the spec that decides the fit.
Package and rework
The SC-70-5 package (also known as SOT-353) is a 5-lead surface-mount case. It reflows well with a standard hot-air station.
