Description

The unity-gain stable LM4913 is both a mono differential output (for bridge-tied loads, or BTL) audio power amplifier and a single-ended (SE) stereo headphone amplifier. Oper-ating on a single 5V supply, the mono BTLmode delivers 2W (typ) to a 4Ω load (Note 1) at 0.3% THD+N. In SE stereo mode, the amplifier will deliver 90mW to 32Ω loads.TheLM4913 features circuitry that suppresses output transients("clicks and pops").

The LM4913 is designed for notebook and other handheld portable applications. It delivers high quality output power from a surface-mount package and requires few external components. The LM4913 is pin and functionally compatible with the TPA0213.

Other features include an active-low micro-power shutdown mode and thermal shutdown protection.

The LM4913 is available a space efficient 10-lead exposed-DAP TSSOP package.
