GENERAL DESCRIPTION
The unity-gain stable Operating on a single 5V supply, the mono BTL mode 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. 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 exposedDAP TSSOP package. Note 1: When operating on a 5VDC supply, an LM4913MH that has been properly mounted to a circuit board will deliver 2W into 4Ω. See the Application Information sections for further information concerning PCB layout suggestions to maximize the LM4913MH’s output power with a 4Ω load.
