SGM8904 - Capless 2Vrms to 3Vrms Line Driver

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 component count and cost.

The device is ideal for single supply electronics where size and cost are critical design parameters.

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 component 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 compliment DAC's and SOC converters. The SGM8904 has build-in shutdown control for Pop&Click-free on/off control.
