SGM8903YTS14G/TR Datasheet PDF - SGMicro

●The SGM8903 is a 3Vrms pop/click-free stereo line driver designed to allow the removal of the output DC-blocking capacitors for reduced component count and cost. The device is ideal for single supply electronics where size and cost are critical design parameters.

●The SGM8903 is capable of driving 3Vrms into a 2.5kΩ load with 5V supply voltage. The device has differential inputs and uses external gain setting resistors that supports a gain range of ±1V/V to ±10V/V.The use of external gain resistors also allows the implementation of a 2nd-order low pass filter to compliment DAC"s and SOC converters. The SGM8903 has build-in shutdown control for pop/click-free on/off control.

●Using the SGM8903 in audio products can reduce component count compared to traditional methods of generating a 3Vrms output. The SGM8903 doesn"t require a power supply greater than 5V to generate an 8.5VPP output, nor does the device require a split rail power supply. The SGM8903 integrates a charge pump to generate a negative supply rail that provides a clean, pop/click-free ground-biased 3Vrms output.

●The SGM8903 is available in Green TSSOP-14 package. It operates over an ambient temperature range of -40℃ to +85℃.
