SGM8904 Capless 2Vrms to 3Vrms Line Driver with Adjustable Gain GENERAL DESCRIPTION The SGM8904 is a 2Vrms to 3Vrms Pop&Click-less stereo line driver designed to allow the removal of the output dc-blocking capacitors for reduced ponent count and cost. The device is ideal for single supply electronics where size and cost are critical design parameters. The SGM8904 is capable of driving 3Vrms into a 2.5kΩ load with 5V supply voltage. The device has single input 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 pliment DAC's and SOC converters. The SGM8904 has build-in shutdown control for Pop&Click-free on/off control. Features z Capless Structure Eliminates Pop/Clicks Eliminates Output DC-Blocking Capacitors Provides Flat Frequency Response DC to 20k Hz z Low Noise and THD Typical SNR = 107d B Typical VN = 8µVrms Typical THD+N = 0.001% (f = 1k Hz) z 2Vrms Output Voltage into 2.5kΩ Load with 3.3V Supply Voltage z 3Vrms Output Voltage into 2.5kΩ Load with 5V Supply Voltage Using the SGM8904 in audio products can reduce ponent count pared to traditional methods of generating a 3Vrms output. The SGM8904 doesn't require a power supply greater than 5V to generate its 8.5VPP output, nor does it require a split rail power supply. The SGM8904 integrates its own charge pump to generate a negative supply rail that provides a clean, pop&click-less ground biased 3Vrms output. APPLICATIONS Set-Top Box LCD TV Blue-Ray DVD-Players Home Theater in a Box The SGM8904 is available in Green MSOP10 package. It operates over an ambient temperature range of -40℃ to +85℃.
