SGM8909
3Vrms Audio Line Driver with Integrated
Filter and Programmable Gain Stage
GENERAL DESCRIPTION
FEATURES
The SGM8909 is a single-ended, 3Vrms stereo audio
line driver with integrated audio filter. The device is
ideal for single supply applications. Capless design
can eliminate output DC-blocking capacitors for
less-component count and low-cost.
Supply Voltage: 2.8V to 5.5V
Capless Structure to Eliminate Pop-Clicks
and Output DC-Blocking Capacitors
Low Noise, Low THD and Low Crosstalk:
SNR = 107dB at Gain = -1, 600Ω Load for 5V VCC
Typical VN = 8.7μVrms from 20Hz to 20kHz at Gain = -1
THD+N = 0.007% for 600Ω Load and Gain = -1
Crosstalk = -87dB at 1kHz
The SGM8909 is capable of driving 3Vrms into a 600Ω
load when VCC is 5V or 30mW into 32Ω headset when
VCC is 3.3V. An integrated charge pump generates a
negative power rail that provides a clean, pop-free
ground offset.
3Vrms Output Voltage into 600Ω Load for 5V VCC
2Vrms Output Voltage into 600Ω Load for 3.3V VCC
Supports 32Ω Headset: 30mW at VCC = 3.3V
Single-Ended Input and Output
The device has a gain programming pin. With a single
resistor from this pin to ground, device gain can be
changed to match the line driver and the codec output
level. Built-in active mute control, -90dB attenuation,
helps for pop-free mute on/off control.
Programmable Gain by Single External Resistor
Active Mute with More than -90dB Attenuation
UVP Function to Eliminate Turn Off Click-Pop Noise
Integrated Audio Filter
Adjustable Power-On Blanking Time to Eliminate
Turn-on Click-Pop Noise
The SGM8909 will be in mute status during power-on
blanking time. External mute control can take over the
mute status before power-on blanking time is over. The
SGM8909 can eliminate power up click-pop noise
perfectly. Using the under-voltage protection (UVP)
function, SGM8909 will minimize the turn off click-pop
noise.
Short-Circuit and Thermal Protection
-40℃ to +85℃ Operating Temperature Range
Available in a Green TSSOP-14 Package

ABSOLUTE MAXIMUM RATINGS
Supply Voltage Range......................................... -0.3V to 6V
OVERSTRESS CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.

ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
RECOMMENDED OPERATING CONDITIONS
Supply Voltage Range........................................2.8V to 5.5V
Operating Temperature Range.......................-40℃ to +85℃
