SGM89112
Capless 3Vrms Line Driver with
8MHz 5th-Order Video Driver
GENERAL DESCRIPTION
FEATURES
The SGM89112 is a 3Vrms pop/click-free stereo line
driver. The device is ideal for single supply applications.
Capless design can eliminate output DC-blocking
capacitors for less-component count and low-cost. The
SGM89112 also has a single rail-to-rail 5th-order video
filter with a slew rate of 33V/µs and a -3dB bandwidth of
8MHz. It can operate from 3.0V to 5.5V power supply.
Supply Voltage Range: 3V to 5.5V
Output Voltage into 2.5kΩ Load
3Vrms at 5V Supply Voltage
Input Voltage Range Includes Ground
Capless Structure
Pop/Click-Free
Eliminates Output DC-Blocking Capacitors
Provides Flat Frequency Response
Video Driver Gain: 6dB
The SGM89112 has single input and is capable of
driving 3Vrms into a 2.5kΩ load with 5V supply voltage.
Build-in shutdown control also helps for pop/click-free
on/off control. The gain can be set by users from ±1V/V
to ±10V/V through external gain setting resistors that
also allows the implementation of a 2nd-order low pass
filter to compliment SOC and DAC's converters. The
video driver of the SGM89112 uses an internal level
shift circuit to allow DC-coupled output and avoid
synchronous pulse clipping.
5th-Order Video Filter
Video Driver can Drive Two Video Loads
Support Single Audio Signal Input
Excellent SD Video Performance
Low Noise and THD
SNR = 107dB (TYP)
VN = 9μVrms (TYP)
THD+N = 0.001% (f = 1kHz)
-40℃ to +85℃ Operating Temperature Range
Available in a Green TSSOP-16 Package
SGM89112 does not require a power supply. An
integrated charge pump generates a 3Vrms output
negative power rail that provides a clean, pop/click-free
ground offset.
APPLICATIONS
LCD TV
The SGM89112 is available in a Green TSSOP-16
package. It operates over an ambient temperature
range of -40℃ to +85℃.

ESD Susceptibility
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.
