APA3160A
20W Stereo Digital Class-D Audio Power Amplifier
Features
General Description
• Operating Voltage: 8.0V~24V for PVDD
The APA3160A 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 APA3160A 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 APA3160A is a slave device receiving clocks from
• Shutdown and Mute Function
external source, and the Class-D’s PWM switching fre-
