SGM4916
88mW, Capless, Stereo Headphone
Amplifier with Shutdown
GENERAL DESCRIPTION
FEATURES
The SGM4916 is stereo headphone amplifier which is
designed for portable applications and can operate
from a 2.7V to 5.5V single supply. Capless design can
produce a ground-referenced output from a single
power supply, and can eliminate output DC-blocking
capacitors for less-component height and low-cost. For
SGM4916B, the internal gain setting (-1.5V/V) is to
further reduce component count. For SGM4916A, the
gain can be adjusted by external feedback resistors.
Supply Voltage Range: 2.7V to 5.5V
• SGM4916A: External Feedback Gain Network
SGM4916B: Fixed -1.5V/V Gain
Capless Structure
Eliminates Ground-Referenced Outputs
Eliminates Output DC-Blocking Capacitors
Provides Flat Frequency Response
• 88mW into 32Ω Load from 5V Power Supply at
THD+N = 0.1% (Typical, per Channel)
• THD+N = 0.034% (f = 1kHz)
The SGM4916 has low quiescent current 2.7mA at 5V
supply, low 0.034% THD+N, 88mW per channel into
32Ω load from 5V power supply at THD+N = 0.1%. The
high supply rejection ratio (PSRR) of -70dB at 217Hz
allows the device to operate from noisy digital supplies
without an additional linear regulator. The device
provides short-circuit and thermal-overload protections.
Build-in shutdown control also helps for pop/click-free
on/off control.
• High PSRR: -70dB (at 217Hz)
• Quiescent Current: 2.7mA (TYP)
• Shutdown Control
• Short-Circuit and Thermal-Overload Protections
• Under-Voltage Lockout Function
• -40℃ to +85℃ Operating Temperature Range
• Available in a Green TQFN-3×3-12L Package
APPLICATIONS
The SGM4916 is available in a Green TQFN-3×3-12L
package. It operates over an ambient temperature
range of -40℃ to +85℃.

OVERSTRESS CAUTION
ABSOLUTE MAXIMUM RATINGS
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 Susceptibility
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.
