Preliminary Datasheet SGM4917 125mW, Capless, Stereo Headphone Amplifier with Shutdown GENERAL DESCRIPTION The SGM4917 stereo headphone amplifier is designed for portable equipment where board space is at a premium.
The SGM4917 uses capless Direct-drive architecture to produce a ground-referenced output from a single power supply, eliminating the need for large DC-blocking capacitors for output, and saving cost, board space, and component height.
Additionally, for SGM4917B and SGM4917C, the gain is set internally (-2V/V or -1.
5V/V), further reducing component count.
For SGM4917A, the Gain can be adjusted by external feedback resistors.
The SGM4917 delivers up to 125mW per channel into a 32...
