SGM4865
2.6W Stereo Audio Power Amplifier
GENERAL DESCRIPTION
FEATURES
The SGM4865 is a stereo audio power amplifier which
operates from 2.6V to 5.5V supply voltage. It can
deliver 2.6W into a 4Ω load from 5V supply at THD+N =
1%. It is designed for portable applications. The
external gain-setting resistors can configure the
unity-gain stable of the device.
• Supply Voltage Range: 2.6V to 5.5V
• 2.6W into 4Ω Load from 5V Supply at
THD+N = 10% (Typical, per Channel)
• Shutdown Current: 0.03μA (TYP)
• Excellent PSRR: Direct Connection to Battery
• No Output Coupling Capacitors
• External Gain Configuration Capability
• Pop/Click Suppression Circuitry
• Unity Gain Stable
The SGM4865 has pop/click suppression circuitry, low
power consumption shutdown mode and thermal
shutdown protection.
• Thermal Shutdown Protection
The SGM4865 is available in a Green TQFN-4×4-16L
package. It operates over an ambient temperature
range of -40℃ to +85℃.
• -40℃ to +85℃ Operating Temperature Range
• Available in a Green TQFN-4×4-16L Package
APPLICATIONS
Cell Phones, PDAs

OVERSTRESS CAUTION
ABSOLUTE MAXIMUM RATINGS
Supply Voltage...................................................................6V
Input Voltage......................................... -0.3V to (VCC) + 0.3V

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.

MM.................................................................................400V
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.
