LM4869 Datasheet Btl Output Stereo Audio Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4869 1.9W Differential Input, BTL Output Stereo Audio Amplifier with Selectable Gain and Shutdown August 2002 LM4869 1.

General Description

The LM4869

Key Features

  • differential stereo inputs, BTL (bridgetied load) outputs, and four externally selectable fixed gains. Operating on a single 5V supply, the LM4869 delivers 1.2W and 1.9W (typ) of output power to an 8Ω and 4Ω BTL load (Note 1), respectively, with less than 1% THD+N. The LM4869’s gain is selected using two digital inputs. The nominal gain values are 6dB, 10dB, 15.6dB, and 21.6dB. The LM4869 is designed for notebook and other handheld portable.
