... Applications information 4 Applications information The STA515W is a dual channel H-bridge that can deliver 20 W per channel into 8 Ω with 10% THD The STA515W converts both DDX and binary-logic-controlled PWM signals into audio power at the load. It includes a logic interface, integrated bridge drivers, high efficiency MOSFET outputs and thermal and short-circuit protection circuitry ...

... INLA = INLB and INRA = INRB, then the corresponding outputs can be shorted together to give OUTLA = OUTLB and OUTRA = OUTRB. Output filter A passive 2nd-order filter is used on the STA515W power outputs to reconstruct an analog audio signal. The system performance can be significantly affected by the output filter design and choice of passive components. ...
