SGM8904
Capless 2Vrms to 3Vrms Line Driver
with Adjustable Gain
GENERAL DESCRIPTION
FEATURES
The SGM8904 is a 2Vrms to 3Vrms pop/click-free
Supply Voltage Range: 3V to 5.5V
stereo line driver. The device is ideal for single supply
Output Voltage into 2.5kΩ Load
applications. Capless design can eliminate output
2Vrms at 3.3V Supply Voltage
DC-blocking capacitors for less-component count and
3Vrms at 5V Supply Voltage
low-cost.
Pop/Click-Free
The SGM8904 has differential inputs and is capable of
Eliminates Output DC-Blocking Capacitors
driving 3Vrms into a 2.5kΩ load with 5V supply voltage.
Provides Flat Frequency Response
Build-in shutdown control also helps for pop/click-free
on/off control. The gain can be set by users from ±1V/V
VN = 5.4μVrms (TYP)
also allows the implementation of a 2nd-order low pass
THD+N = 0.001% (f = 1kHz)
filter to compliment SOC and DAC's converters.
integrated charge pump generates a 3Vrms output
negative power rail that provides a clean, pop/click-free
Low Noise and THD
SNR = 114dB (TYP)

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.
Failure to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation to complete 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.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.
