What the inverting charge pump does for the rail
The MAX1697TEUT-T is an inverting charge pump — it takes a positive input voltage and generates a negative output rail without an inductor. That is the part's whole job: produce a clean negative supply for op-amps, comparators, or bias circuits from a single positive rail.
Lifecycle and compliance — what it means for a BOM line
One catch: it is marked RoHS non-compliant. That means it contains lead (or another restricted substance) above the RoHS threshold. If your BOM requires full RoHS compliance for the end-market (EU, California, etc.), this part will not pass without an exemption. For non-RoHS projects or legacy designs that already have a leaded-solder process, it is fine.
Package note — Bulk means loose units
The listed package is Bulk — loose units in a bag or tube, not tape-and-reel. That is fine for prototyping, bench work, or small-run production. If your pick-and-place line expects reels, you will need to hand-place or request a different packaging option from the supplier.
