SGM4809
Dual 158mW Headphone Amplifier
with Active Low Shutdown Mode
GENERAL DESCRIPTION
FEATURES
The SGM4809 is a dual audio power amplifier with
active low shutdown mode. It is designed to maximize
audio performance in portable applications. The audio
power amplifier is designed for the portable application
that needs low-component count and can operate from
a single 2.5V to 5.5V power supply. Under the condition
of using a 5.0V power supply to drive a 16Ω speaker, it
can deliver a continuous average power of 158mW per
channel, and the distortion (THD+N) is typically 0.1%.
• Supply Voltage Range: 2.5V to 5.5V
• Active Low Shutdown Mode
• 158mW into 16Ω Load from 5V Power Supply at
THD+N = 0.1% (Typical, per Channel)
• 87mW into 32Ω Load from 5V Power Supply at
THD+N = 0.1% (Typical, per Channel)
• Unity Gain Stable
• Shutdown Current: 0.6μA (TYP)
• Shutdown Pin is Compatible with 1.8V Logic
• Pop/Click Reduction Circuitry
The SGM4809 provides an active-low, micro-power
consumption shutdown mode which is controlled
externally and an internal thermal shutdown protection.
• -40℃ to +85℃ Operating Temperature Range
• Available in a Green MSOP-8 Package
SGM4809 is applied to low power portable systems.
Bootstrap capacitors or snubber networks are not
needed.
APPLICATIONS
Mobile Phone
The SGM4809 provides an externally controlled gain
(with resistors), as well as an externally controlled
turn-on time (with the bypass capacitor) for maximum
flexibility.
Portable Systems
Headphone Amplifier
Notebook Computers
Microphone Preamplifier
PDAs
The SGM4809 is available in a Green MSOP-8
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.
