Overview
SGM4918 80mW, Capless, Stereo Headphone Amplifier with Shutdown GENERAL 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 component height.
Additionally, for SGM4918B, the gain is set internally (-2V/V), further reducing component count.
For SGM4918A, the gain can be adjusted by external feedback resistors.
The SGM4918 delivers up to 80mW per channel into a 32Ω load and has low 0.
03% THD+N.
