... Technical information 4 Technical information The STA510A is a dual channel H-bridge that is able to deliver 100 W per channel (into = 6 Ω with THD = 10% and conjunction with a pulse-width modulator driver such as the STA321 or STA309A. The STA510A converts ternary-, phase-shift- or binary-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 ...

... Parallel output / high current operation When using the DDX mode output, the STA510A outputs can be connected in parallel in order to increase the output current capability to a load. In this configuration the STA510A can provide up to 200 W into a 3-Ω load. This mode of operation is enabled with the pin CONFIG (pin 24) connected to pin VDD. The ...
