Overview of TPA6304QDDVRQ1

The TPA6304-Q1 device is a four-channel analog-input Class-D Burr-Brown™ audio amplifier that implements a 2.1 MHz PWM switching frequency that enables a cost optimized solution in a very small 2.7 cm2 PCB size, high impedance single ended inputs and full operation down to 4.5 V for start/stop events.

The TPA6304-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 can be set either above the AM band, which eliminates the AM band interference and reduces output filter size and cost, or below AM band to further optimize efficiency.

The device is offered in a 44 pin HTSSOP package with the exposed thermal pad up.
