The GameBoy sound chip exists to synthesize simple sounds for music and sound effects. It tries to do work so the CPU doesn’t have to, since the CPU is fairly slow and might not have time. (Today, “sound cards” are mostly just DACs, because modern computers have the resources to generate sounds in software.)

The Game Boy amplifier chip has a design very similar to the popular LM380 power audio amplifier chip (1972), so I'll start with an overview of how the LM380 works. (See the footnote 5 for details.) The LM380 has positive and negative inputs and an output that amplifies the difference between the inputs by a fixed factor of 50.
