Description
General part information
TPA6404-Q1 Series
The TPA6404-Q1 device is a four-channel analog-input Class-D audio amplifier that implements a 2.1MHz PWM switching frequency that enables a cost optimized solution in a very small 4.5cm2 PCB size, full operation down to 4.5V for start/stop events, and exceptional sound quality with up to 100kHz audio bandwidth.
The TPA6404-Q1 Class-D audio amplifier has an optimal design for use in entry level automotive head units that provide analog audio input signals as part of their system design.
The Class-D topology dramatically improves efficiency over traditional linear amplifier solutions.
