The LM4871LD is a mono bridged audio power amplifier designed by Texas Instruments, offering 3W of continuous average power into a 3 Ohm load with less than 10% THD when powered by a 5V supply. This amplifier is suitable for portable computers, desktop computers, and low voltage audio systems.
Key features include no requirement for output coupling capacitors, bootstrap capacitors, or snubber circuits, and unity-gain stability. The device operates within a supply voltage range of 2.0V to 5.5V and includes a micropower shutdown mode that activates when VDD is applied to the SHUTDOWN pin, reducing quiescent current to 0.6µA typical.
The LM4871LD is available in an 8-WSON package with dimensions of 4mm x 4mm. It operates across a temperature range of -40°C to 85°C. The amplifier provides a typical output power of 3W into a 3 Ohm load and 2.5W into a 4 Ohm load at 10% THD+N, 1kHz. For 8 Ohm loads, the typical output power is 1.5W.
This amplifier is pin compatible with the LM4861 and offers external gain configuration capability. Its architecture is Class AB, with analog input and hardware control interface.
