GENERAL DESCRIPTION SGM8905 Capless 2Vrms to 3Vrms Line Driver with Adjustable Gain Features The SGM8905 is a 2Vrms to 3Vrms pop/click-free stereo line driver. The device is ideal for single supply applications. Capless design can eliminate output DC-blocking capacitors for less-ponent count and low-cost. The SGM8905 has differential inputs and is capable of driving 3Vrms into a 2.5kΩ load with 5V supply voltage. Build-in shutdown control also helps for pop/click-free on/off control. The gain can be set by users from ±1V/V to ±10V/V through external gain setting resistors that also allows the implementation of a 2nd-order low pass filter to pliment SOC and DAC's converters. SGM8905 does not require a power supply. An integrated charge pump generates a 3Vrms output negative power rail that provides a clean, pop/click-free ground offset. The SGM8905 is available in a Green MSOP-10 (Exposed Pad) package. It operates over an ambient temperature range of -40℃ to +85℃. - Supply Voltage Range: 3V to 5.5V - Output Voltage into 2.5kΩ Load - 2Vrms at 3.3V Supply Voltage - 3Vrms at 5V Supply Voltage - Capless Structure - Pop/Click-Free - Eliminates Output DC-Blocking Capacitors - Provides Flat Frequency Response - Low Noise and THD - SNR = 114d B (TYP) - VN = 5.4μVrms (TYP) - THD+N = 0.001% (f = 1k Hz) - -40℃ to +85℃ Operating Temperature Range - Available in a Green MSOP-10 (Exposed Pad) Package APPLICATIONS LCD TV Set-Top Box Home Theater Blue-Ray DVD-Players SG Micro Corp .sg-micro.
