The LM49150 is a fully integrated audio subsystem designed for portable handheld applications such as cellular phones.

a patented, ultra low EMI PWM architecture that significantly reduces RF emissions while preserving audio quality. The 42mW/channel headphone drivers feature National’s ground referenced architecture that creates a ground-referenced output from a single supply, eliminating the need for bulky and expensive DC-blocking capacitors, saving space and minimizing cost. The LM49150 features a fully differential mono input, and two single-ended stereo inputs. The three inputs can be mixed/ multiplexed to.
