Integrated Class D Amplifier

MA5302MS

The single-supply configuration uses a virtual GND which sits in the middle of the power supply rail. The front-

end section of the amplifier refers to the virtual GND as a reference. This method uses differential input to

receive an input signal from a different voltage potential. It is recommended to allow input capacitors to fully

settle to steady-state values before releasing the CSD pin to start PWM oscillation. The load current and

inductor ripple current flow through the bus splitting capacitor.

Balanced Tied Load (BTL) output takes two output legs for speaker output. It doubles output power with

double load impedance. Any load current does not flow through supply dividing capacitor; therefore BTL

configuration is free from GND fluctuations. Also, the bus splitting capacitor can be much smaller. Higher

output power and absence of GND fluctuation make BTL suitable for subwoofer applications.
