SGM8903YTS14G/TR

The SGM8903 is a 3Vrms pop/click-free stereo line driver. This device is well-suited for single-supply applications. The capacitor-free design eliminates output DC-blocking capacitors, reducing component count and lowering cost. The SGM8903 features differential inputs and is capable of driving 3Vrms into a 2.5kΩ load at a 5V supply voltage. The built-in shutdown control also enables pop/click-free switching. Users can set the gain between ±1V/V and ±10V/V via external gain-setting resistors, which also allow implementation of a second-order low-pass filter for use with SOC and DAC converters. The SGM8903 requires no power supply. An integrated charge pump generates a negative supply rail for the 3Vrms output, providing a clean, pop/click-free ground offset. The SGM8903 is available in a RoHS-compliant TSSOP-14 package. Its operating ambient temperature range is -40°C to +85°C.
