General Description
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.
Key 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 resistors. Key Specifications n THD+N at 1W into 8Ω n Output power into 8Ω at 1kHz at 10%THD+N n Shutdown Current 0.5% (max) 1.5W (typ) 0.6µA (typ) Features n No output coupling capacitors, bootstrap capaci.
