SGM4995
1.3W Mono Fully Differential
Audio Power Amplifier
GENERAL DESCRIPTION
FEATURES
The SGM4995 is a fully differential audio power
amplifier which operates from 2.5V to 5.5V power
supply. It can deliver 1.3W into a 8Ω load from 5V
supply at THD+N = 1%. It is designed for portable
applications.
• Supply Voltage Range: 2.5V to 5.5V
• 1.3W into 8Ω Load from 5V Supply at
THD+N = 1% (TYP)
• High PSRR
• Low Shutdown Current
• Pop/Click Suppression Circuitry
• Support Single-Ended or Differential Input
• Thermal Overload Protection Circuitry
• External Gain Configuration Capability
• -40℃ to +85℃ Operating Temperature Range
• Available in a Green TDFN-2×2-8L Package
The SGM4895 has pop/click suppression circuitry, low
power consumption shutdown mode and thermal
shutdown protection.
Bootstrap capacitors or output coupling capacitors are
not needed.
The SGM4995 is available in a Green TDFN-2×2-8L
package. It operates over an ambient temperature
range of -40℃ to +85℃.

Input Voltage Range............................. -0.3V to (VCC) + 0.3V
Typical Thermal Resistance
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.

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.
