Specifications

The SGM4918 is stereo headphone amplifier which is designed for portable applications and can operate from a 2.7V to 5.1V single supply.
Capless design can produce a ground-referenced output from a single power supply, and can eliminate output DC-blocking capacitors for less-component height and low-cost.
For SGM4918B, the internal gain setting (-2V/V) is to further reduce component count.
For SGM4918A, the gain can be adjusted by external feedback resistors.
The SGM4918 has low quiescent current 5.8mA at 5V supply, low 0.03% THD+N, 80mW per channel into 32Ω load from 5V power supply at THD+N = 0.1%.
The high supply rejection ratio (PSRR) of -78dB at 217Hz allows the device to operate from noisy digital supplies without an additional linear regulator.
The device provides short-circuit and thermal-overload protections.
Build-in shutdown control also helps for pop/click-free on/off control.
Supply Voltage Range: 2.7V to 5.1V
