Additional Details

The APA3012XAI-TRL operates from a single power supply voltage, typically in the range of 2.5V to 5.5V. It can deliver up to 3W of output power into a 4Ω load. The amplifier's filter-free modulation scheme eliminates the need for external output filters, reducing the bill of materials (BOM) cost and simplifying the PCB layout. The integrated gain setting allows for easy configuration of the amplifier's gain using external resistors. The APA3012XAI-TRL also includes comprehensive protection features, such as short-circuit protection, over-temperature protection, and under-voltage lockout (UVLO), to ensure reliable operation and prevent damage. It is available in a space-saving package, making it suitable for portable and space-constrained applications. The TRL suffix indicates that the part is tape and reel.
