LM4869 - BTL Output Stereo Audio Amplifier

Description

The LM4869

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.
