SGM8904YMS10G/TR

The SGM8904 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-component count and low-cost. The SGM8904 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 ±1/N to ±10/N through external gain setting resistors that also allows the implementation of a 2nd-order low pass filter to compliment SOC and DAC's converters. SGM8904 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 SGM8904 is available in a Green MSOP-10 package. It operates over an ambient temperature range of -40°C to +85°C.
