Ground Reference Output
nating component height, and improving the low frequency
response.
- No Output Capacitor Required (for DC Blocking)
- Save the PCB Space
The internal selectable gain (0dB or 6dB) can minimize
the external component counts and save the PCB space.
- Reduce the BOM Costs
- Improve the Low Frequency Response

Function Description
Headphone Driver Operation
Shutdown Function
In order to reduce power consumption while not in use,
the APA2177 contains shutdown controllers to externally
VDD
turns off the amplifier bias circuitry. This shutdown feature turns the amplifier off when logic low is placed on the
VOUT
VDD/2
SDN pins for the APA2177. The trigger point between a
logic high is 1.0V and logic low level is 0.35V. It is recomGND
mended to switch between ground and the supply voltage VDD to provide maximum device performance. By
Conventional Headphone Driver
switching the SDN pins to a low level, the amplifier enters
a low-consumption current circumstance, charge pump
VDD
is disabled, and IDD for the APA2177 is in shutdown mode.
In normal operating, the APA2177’s SDN pins should be
pulled to a high level to keep the IC out of the shutdown
mode. The SDN pins should be tied to a definite voltage
VOUT
GND
to avoid unwanted circumstance changes.
VSS
Cap-free Headphone Driver
Figure 1. Cap-free Operation
The APA2177’s headphone drivers use a charge pump
to invert the positive power supply (VDD) to negative power
supply (VSS), see figure1. The headphone drivers operate at this bipolar power supply (VDD and VSS) and the outputs reference refers to the ground. This feature eliminates the output capacitor that is using in conventional
single-ended headphone drive amplifier. Compare with
the single power supply amplifier, the power supply range
has almost doubled.
Thermal Protection
The thermal protection circuit limits the junction temperature of the APA2177. When the junction temperature exceeds TJ = +150oC, a thermal sensor turns off the driver,
allowing the devices to cool. The thermal sensor allows
the driver to start-up after the junction temperature down
about 125oC. The thermal protection is designed with a
25oC hysteresis to lower the average TJ during continuous thermal overload conditions, increasing lifetime of
the ICs.

The optimum decoupling is achieved by using two differ-
In the typical application, an input capacitor, Ci, is required
ent types of capacitor that target on different types of noise

When polarized capacitors are used, the negative side of
the capacitor should face the amplifier input in most applications as the DC level there is held at GND, which is
likely lower than the source DC level. Please note that it
is important to confirm the capacitor polarity in the
application.
Power Supply Decoupling (Cs)
The APA2177 is a high-performance CMOS audio amplifier that requires adequate power supply decoupling to
ensure the output total harmonic distortion (THD+N) is
as low as possible. Power supply decoupling also prevents the oscillations causing by long lead length between the amplifier and the speaker.

1. All components should be placed close to the APA2177.
For example, the input capacitor (CiR, CiL) should be
close to APA2177 input pins to avoid causing noise
coupling to APA2177 high impedance inputs; the
decoupling capacitor (CS) should be placed by the
APA2177 power pin to decouple the power rail noise.
2. The output traces should be short, wide (>50mil), and
symmetric.
3. The input trace should be short and symmetric.
4. The power trace width should be greater than 50mil.
5. The input trace and output trace should be away from
CCPF and CCPB possible.
