Mono Class AB Audio Sub-System With A True-Ground Headphone AmplifierThe LM49100 is a fully integrated Audio subsystem capable of delivering 1.275W of continuous average power into a mono 8&
bridged-tied load (BTL) with 1% THD+N and with a 5V power supply. The LM49100 also has a stereo true-ground Headphone Amplifier
capable of 50mW per channel of continuous average power into a 32& single-ended (SE) loads with 1% THD+N.
The LM49100 has three input channels. One pair of SE inputs CAN be used with a stereo signal. The other input channel is fully differential and may be used with a mono input signal. The LM49100 features a 32-step digital Volume Control and ten distinct output modes. The mixer, Volume Control and device mode select are controlled through an I 2C compatible Interface Thermal overload protection prevent the device from being damaged during fault conditions. Superior click and pop suppression eliminates audible transients on power-up/down and during shutdown. By National Semiconductor Corporation |
