SGM8905
Capless 2Vrms to 3Vrms Line
Driver with Adjustable Gain
GENERAL DESCRIPTION
FEATURES
The SGM8905 is a 2Vrms to 3Vrms pop/click-free 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 SGM8905 is capable of driving 3Vrms into a 2.5k
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 SGM8905 has build-in shutdown control for
pop/click-free on/off control.
Using the SGM8905 in audio products can reduce
component count compared to traditional methods of
generating a 3Vrms output. The SGM8905 doesn't
require a power supply greater than 5V to generate an
8.5VPP output, nor does the device require a split rail
power supply. The SGM8905 integrates a charge pump
to generate a negative supply rail that provides a clean,
pop/click-free ground-biased 3Vrms output.

NOTES:
1. In order to get good performance, it’s important to select the right CPUMP, CPVSS and CBYP in application. All tests are performed with
circuit set up with X5R and X7R capacitors. Capacitors having high dissipative loss, such as Y5V capacitor, may cause performance
degradation and unexpected system behavior.
2. A 10kresistor must be serially connected to EN pin.
