General Description
The APA2176/2176A is a stereo, fixed gain, and cap-free
headphone driver which is available in TQFN4x4 20-pin,
TQFN3x3 16-pin (APA2176A) or TSSOP-16 package. Dual
supply voltage provides higher efficiency and better power
ripple rejection.
The APA2176/2176A is designed with ground-reference
output and no need the output capacitors for DC blocking.
The advantages of eliminating the output capacitor are
saving the cost, PCB’s space, and component height.
The built-in gain setting can minimize the external com-
ponent counts and save the PCB space. High PSRR pro-
vides increased immunity to noise and RF rectification. In
addition to these features, a fast start-up time and small
package size make the APA2176/2176A an ideal choice
for portable multimedia devices.
Moreover, the APA2176/2176A is also equipped other
features. For example, at THD+N=1%, it is capable of
driving 200mW at VDD=3.3V, PVDD=5.0V into 16. In
addition, it provides thermal and short circuit protections.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).

Note1: Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are
stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recom-
mended operating conditions" is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device
