Capless 3Vrms Line Driver with Adjustable Gain

The SGM8903 is a 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 SGM8903 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 compliment SOC and DAC's converters.

SGM8903 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 SGM8903 is available in a Green TSSOP-14 package. It operates over an ambient temperature range of -40 to +85.
