PDIP16 (16-pin Plastic Dual In-line Package), which is ideal for through-hole mounting and prototyping.

Unlikely. Re-check your PCB layout. The PDF datasheet’s thermal section probably recommends adding vias under the IC to a ground plane. Also verify that the SLEEP pin is not floating.

Control and Enable pins used to toggle operational modes or activate the IC.
