Small PDF, roughly 11 KB, associated with the ICL8038 function generator chip in P (plastic package) form according to the name suffix. Its size indicates a single page or brief excerpt rather than the complete datasheet, perhaps pinout or ordering information. Use it as a quick reference only, and fall back on the full ICL8038 documentation for frequency equations, distortion trimming and electrical limits. Always check the package and markings on the chip fitted to the board.
