1 pcs : TPA6404QDKQRQ1 - Audio Amplifiers Automotive, 45-W, 2-MHz, 4-ch 4.5- to 18-V supply analog input Class-D audio amplifier

TPA6404-Q1 Class-D Audio Amplifier Texas Instruments TPA6404-Q1 Class-D Audio Amplifier is a four-channel analog-input Class-D audio amplifier that implements a 2.1MHz PWM switching frequency. This switching frequency 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 Texas Instruments TPA6404-Q1 Class-D audio amplifier has an optimal design for entry-level automotive head units that provide analog audio input signals as part of a system design. The Class-D topology dramatically improves efficiency over traditional linear amplifier solutions. The output switching frequency operates above the AM band, eliminating the AM band interference and reducing the output filter size and cost.
