SGM89000

Capless 2Vrms Line Driver

with Adjustable Gain

GENERAL DESCRIPTION

FEATURES

The SGM89000 is a 2Vrms 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.

 Capless Structure

Eliminates Pop/Clicks

Eliminates Output DC-Blocking Capacitors

Provides Flat Frequency Response from DC to

20kHz

 Low Noise and THD

Typical SNR = 114dB

The SGM89000 is capable of driving 2Vrms into a

2.5kΩ load with 3.3V supply voltage. The device has

differential inputs 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

SGM89000 has build-in shutdown control for

pop/click-free on/off control.

Typical V_N= 5.5μVrms

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

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

Supply Voltage

 Differential Input

 -40℃ to +85℃ Operating Temperature Range

 Available in the Green TSSOP-14 Package

APPLICATIONS

Using the SGM89000 in audio products can reduce

component count compared to traditional methods of

generating a 2Vrms output. The SGM89000 doesn't

require a power supply greater than 3.3V to generate a

5.6V_PPoutput, nor does the device require a split rail

power supply. The SGM89000 integrates a charge

pump to generate a negative supply rail that provides a

clean, pop/click-free ground-biased 2Vrms output.

Set-Top Box

LCD TV

Blue-Ray DVD-Players

Home Theater in a Box

The SGM89000 is available in Green TSSOP-14

package. It operates over an ambient temperature

range of -40℃ to +85℃.
