Product Summary
The LM4865MM is a mono bridged audio power amplifier with DC volume control, capable of delivering 750 mW of continuous average power into an 8W load with less than 1% THD from a 5V power supply. Switching between bridged speaker mode and headphone (single ended) mode is accomplished via a headphone sense pin. In addition, the LM4865MM is set into low current consumption shutdown mode (0.7 μA typical) by lowering the DC Vol/SD pin to below 0.3V. Boomer audio power amplifiers are designed specifically to provide high power audio output, with quality sound, from a low supply voltage source while requiring the minimal amount of external components. Applications include: GSM phones and accessories, DECT, office phones, Hand held radio and Other portable audio devices.
