商品信息

GENERAL DESCRIPTIONThe 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℃.
