The LM48311TL/NOPB from Texas Instruments is a high-efficiency, mono, Class-D audio power amplifier capable of delivering 2.6W of output power into a 4Ω load. It features an analog input and a fixed 6dB gain, simplifying integration into audio systems.
Designed for low power consumption, this amplifier operates from a single supply voltage between 2.4V and 5.5V. Key electrical specifications include a typical THD+N of 0.03% at 1kHz, and efficiencies up to 88% at 5V. The device also includes features such as output short circuit protection with auto-recovery, "click and pop" suppression, and a micro-power shutdown mode.
The LM48311TL/NOPB is available in a space-saving DSBGA package, measuring 3.0625 mm². Its filterless design and Ultra-Low EMI characteristics, along with the E2S system, help reduce electromagnetic interference while preserving audio quality and efficiency. This makes it suitable for various audio applications where space and power are critical.
This amplifier passes FCC Class B Radiated Emissions with 20 inches of cable, indicating good EMI performance in system integration. The operating temperature range is from -40°C to 85°C, ensuring reliable performance in diverse environments.
