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 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 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.
