SGM4914 95mW, Capless, Stereo Headphone Amplifier with Shutdown
GENERAL DESCRIPTION
The SGM4914 stereo headphone amplifier is designed for portable equipment where board space is at a premium. The SGM4914 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 SGM4914B and SGM4914C, the gain is set internally (-2V/V or -1.5V/V), further reducing component count. For SGM4914A, the gain can be adjusted by external feedback resistors.
The SGM4914 delivers up to 95mW per channel into a 32Ω load and has low 0.01% THD+N.
