LM48510 Datasheet Boosted Class D Audio Power Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: www.DataSheet4U.com LM48510 Boosted Class D Audio Power Amplifier November 2006 LM48510 Boosted Class D Audio Power.

General Description

The LM48510 integrates a boost converter with a high efficiency mono, Class D audio power amplifier to provide 1.2W continuous power into an 8Ω speaker when operating on a 3.3V power supply with boost voltage (PV1) of 5.0V.

When operating on a 3.3V power supply, the LM48510 is capable of driving a 4Ω speaker load at a continuous average output of 1.7W with less than 1% THD+N.

The Class D amplifier is a low noise, filterless PWM architecture that eliminates the output filter, reducing external component count, board area consumption, system cost, and simplifying design.

Key Features

  • a low-power consumption shutdown mode. Shutdown may be enabled by driving the Shutdown pin to a logic low (GND). The gain of the Class D is externally configurable which allows independent gain control from multiple sources by summing the signals. Output short circuit and Thermal shutdown protection prevent the device from damage during fault conditions. Superior click and pop suppression eliminates audible transients during power-up and shutdown. Key Specifications.
  •  Quiescent Power Supply.
