LM4869
1.
9W Differential Input, BTL Output Stereo Audio
Amplifier with Selectable Gain and Shutdown
General 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 portabl...
