SGM4918 Description
The SGM4918 stereo headphone amplifier is designed for portable equipment where board space is at a premium. The SGM4918 uses capless architecture to produce a ground-referenced output from a single power supply, eliminating the need for large DC-blocking capacitors for output, saving cost, board space, and ponent height. Additionally, for SGM4918B, the gain is set internally (-2V/V), further reducing ponent count.
