Description

General part information

LM4866 Series

The LM4866 is a bridge-connected (BTL) stereo audio power amplifier which, when connected to a 5V supply, delivers 2.2W to a 4Ω load or 2.5W to a 3Ω load with less than 1.0% THD+N (see Notes below).

With the LM4866 packaged in the WQFN, the customer benefits include low thermal impedance, low profile, and small size. This package minimizes PCB area and maximizes output power.

The LM4866 features an externally controlled, low-power consumption shutdown mode, and thermal shutdown protection. It also utilizes circuitry to reduce "clicks and pops" during device turn-on.
