APA3175
20W Stereo Digital Class-D Audio Power Amplifier with EQ and DRC
Features
General Description
Operating Voltage: 4.5V~24V for PVDD
The APA3175 is a digital input, stereo, high efficiency,
3.0V~3.6V for DVDD and AVDD
High Efficiency Class-D Operation Eliminate the
Class-D audio amplifier available in a TQFP7x7-48P
package.
Need of Heatsinks
The APA3175 accepts the digital serial audio data and
Digital Serial Audio Input (Stereo Output)
using the digital audio processor to convert the audio
I2C Control Interface
data becomes the stereo Class-D output speaker
Sampling Rate can Support from 32kHz to 192kHz amplifier. This provides the seamless integration between
Separated Volume Control from 24dB to Mute
the codec and the speaker amplifier.
Soft Mute (50% Duty Cycle)
The APA3175 is a slave device receiving clocks from ex-
Programmable Dynamic Range Compression
ternal source, and the Class-Ds PWM switching fre-

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 Greento 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
reliability.

Note 2: θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. The exposed pad
of TQFP7X7-48P is soldered directly on the PCB.
Note 3: The case temperature is measured at the center of the exposed pad on the underside of the TQFP7X7-48P package.
