The TPA6404-Q1 device is a four-channel analog-input Class-D audio amplifier that implements a 2.1 MHz PWM switching frequency that enables a cost optimized solution in a very small 4.5 cm2 PCB size, full operation down to 4.5 V for start/stop events, and exceptional sound quality with up to 100 kHz 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.
The output switching frequency operates above the AM band, which eliminates the AM band interference and reduces the output filter size and cost.
The device is offered in a 56 pin HSSOP package with the exposed thermal pad up.
