LM4870 1.1W Audio Power Amplifier

The LM4870 is a bridge-connected audio power amplifier capable of delivering 1.1W of continuous average power to an 8Ω load with less than 0.5% THD+N over the audio spectrum from a 5V power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a m.

LM4870 Features

* an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. It also includes two headphone control inputs and a headphone sense output for external monitoring. The LM4870 is unity-gain stable and the gain is set using external resistor
