Texas Instruments TAS6424QDKQRQ1

The TAS6424-Q1 device is a Four-channel digital-input Class-D audio amplifier that implements a 2.1 MHz PWM switching frequency that enables a cost-optimized solution in a very small PCB size, full operation down to 4.5 V for start/stop events, and exceptional sound quality with up to 40 kHz audio bandwidth

The TAS6424-Q1 Class-D audio amplifier is designed for use in automotive head units and external amplifier modules. The device provides four channels at 27 W into 4 Ω at 10% THD+N and 45 W into 2 Ω at 10% THD+N from a 14.4-V supply and 75 W into 4 Ω at 10% THD+N from a 25-V supply. 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 optimize efficiency.

For a pin compatible two-channel amplifier, see the TAS6422-Q1

The device is offered in a 56-pin HSSOP PowerPAD™ package with the exposed thermal pad up.
