Capless 2Vrms To 3Vrms Line Driver With Adjustable Gain Integrated
Circuit IC
The SGM8902 is a 2Vrms to 3Vrms pop/click-freestereo line driver.
The device is ideal for single supplyapplications. Capless design
can eliminate outputDC-blocking capacitors for less-component count
andlow-cost.The SGM8902 has differential inputs and is capable
ofdriving 2Vrms into a 2.5kΩ load with 3.3V supplyvoltage. Build-in
shutdown control also helps forpop/click-free on/off control. The
gain can be set byusers from ±1V/V to ±10V/V through external
gainsetting resistors that also allows the implementation ofa
2nd-order low pass filter to compliment SOC andDAC's
converters.SGM8902 does not require a power supply. Anintegrated
charge pump generates a 2Vrms outputnegative power rail that
provides a clean, pop/click-freeground offset.The SGM8902 is
available in a Green TSSOP-14package. It operates over an ambient
temperaturerange of -40℃ to +85℃
