Additional Details

The uPC254A's datasheet specifies the maximum output power, typically measured in watts, at a given load impedance (e.g., 4 ohms or 8 ohms). The distortion is typically specified as Total Harmonic Distortion (THD) and is usually very low at typical operating power levels. The operating voltage range is important to consider when selecting a power supply. The built-in protection circuits are crucial for preventing damage to the IC under fault conditions. Refer to the NEC datasheet for detailed specifications, application circuits, and thermal considerations. Proper heatsinking is often required to dissipate heat generated by the IC at higher power levels.
