1.9w Differential Input, Btl Output Stereo Audio Amplifier With Selectable Gain And Shutdown

The LM4869 features differential stereo inputs, BTL (bridge- tied 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 8 and 4 BTL load (Note 1), respectively, with less than 1% THD+N. The LM4869s gain is selected using two digital inputs. The nomi- nal gain values are 6dB, 10dB, 15.6dB, and 21.6dB. The LM4869 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. Other features include an active-low micropower shutdown mode input and thermal shutdown protection. By National Semiconductor Corporation
