Additional Details:

The TB2132FNG typically operates with a single low-voltage power supply, making it suitable for battery-powered applications. The filterless Class-D design reduces electromagnetic interference (EMI), simplifying PCB layout. Gain adjustment is achieved through external resistors, allowing designers to fine-tune the amplifier's output level. The built-in protection circuits provide robust operation, preventing damage from common fault conditions. The shutdown mode minimizes power consumption when the amplifier is not in use, further extending battery life. Detailed specifications, including output power capabilities and operating voltage ranges, can be found in the product datasheet.
