The LM4860 is a bridge-connected audio power amplifier capable of delivering 1W of continuous average power to an 8Ω load with less than 1% THD+N over the audio spectrum from a 5V power supply.
The LM4860 is a bridge‑connected audio power amplifier capable of delivering 1 W continuous average power into an 8 Ω load with less than 1 % THD+N over the audio spectrum from a 5 V supply. It features a low‑power shutdown mode, thermal shutdown protection, and two headphone control inputs with a headphone sense output.
The document provides key specifications, typical application circuits, external component descriptions, performance characteristics, and detailed design information such as bridge configuration, power dissipation calculations, supply bypassing, shutdown function, and headphone control operation.
| THD+N | ≤ 1 % at 1 W (1 kHz) |
|---|---|
| Supply Voltage | 2.7 V – 5.5 V |
| Maximum Power Dissipation | ≈ 625 mW |
It operates from a supply voltage of 2.7 V to 5.5 V.
No, the LM4860 does not require output coupling capacitors, bootstrap capacitors, or snubber circuits.
