Half Digital Sine Generator

A 3-bit, Diode-rom-based purely digital sine wave generator for one half of a cycle. Could be made more efficient by only using data for a quarter sine wave, then mirroring, but was too lazy to do that. If the analog output is inverted when the fourth bit is on, and then smoothed, a full smooth digitally made sine wave would appear, however due to space limitations I didn't do that. The Selective inverter circuit i made accomplishes the latter goal.
