DESCRIPTION  
Mono Earpiece Amplifier  
The LM49150 is a fully integrated audio subsystem  
designed for portable handheld applications such as  
cellular phones. Part of TI's PowerWise™ product  
family, the LM49150 consumes very low power in the  
various modes of operation and still providing great  
audio performance. The LM49150 combines a 1.25W  
mono E2S (Enhanced Emission Suppression) class D  
amplifier, 135mW Class AB earpiece amplifier,  
42mW/channel stereo ground reference headphone  
amplifiers, volume control, and mixing circuitry into a  
single device.

KEY SPECIFICATIONS  
The filterless class D amplifier delivers 1.25W into an  
8Ω load with <1% THD+N with a 5V supply. The E2S  
class D amplifier features a patented, ultra low EMI  
PWM architecture that significantly reduces RF  
emissions while preserving audio quality. The  
42mW/channel headphone drivers feature TI’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.

Output power at VDD = 3.3V:  
The LM49150 features a fully differential mono input,  
and two single-ended stereo inputs. The three inputs  
can be mixed/multiplexed to either the speaker or  
headphone amplifiers. Each input channel has an  
independent, 32-step digital volume control. The  
headphone output stage features an additional, 8-  
step gain control, while the speaker output stage has  
a selectable 6dB or 12dB gain. The mixer, volume  
control and device mode select are controlled through  
an I2C compatible serial interface.
