SGM8904

Capless 2Vrms to 3Vrms Line Driver

with Adjustable Gain

GENERAL DESCRIPTION

FEATURES

● Capless Structure

The SGM8904 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.

Eliminates Pop/Clicks

Eliminates Output DC-Blocking Capacitors

Provides Flat Frequency Response from DC to 20kHz

● Low Noise and THD

Typical SNR = 114dB

Typical V_N= 5.4μVrms

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.

Typical THD+N = 0.001% (f = 1kHz)

● 2Vrms Output Voltage into 2.5kΩ Load with 3.3V

Supply Voltage

● 3Vrms Output Voltage into 2.5kΩ Load with 5V

Supply Voltage

● -40℃ to +85℃ Operating Temperature Range

● Available in the Green MSOP-10 Package

Using the SGM8904 in audio products can reduce

component count compared to traditional methods of

generating a 3Vrms output. The SGM8904 doesn't

require a power supply greater than 5V to generate an

8.5V_PPoutput, nor does the device require a split rail

power supply. The SGM8904 integrates a charge pump

to generate a negative supply rail that provides a clean,

pop/click-free ground-biased 3Vrms output.

APPLICATIONS

Set-Top Box

LCD TV

Blue-Ray DVD-Players

Home Theater in a Box

The SGM8904 is available in Green MSOP-10 package.

It operates over an ambient temperature range of -40℃

to +85℃.
