Description
The LM4935 is an integrated audio subsystem that supports both analog and digital audio functions. The
LM4935 includes a high quality stereo DAC, a mono ADC, a multi-purpose SAR ADC, a stereo
headphone amplifier, which supports output cap-less (OCL) or AC-coupled (SE)modes of operation, a
mono earpiece amplifier and a mono high efficiency loudspeaker amplifier. It is designed for demanding
applications in mobile phones and other portable devices.
The LM4935 features a bi-directional I2S serial interface for full range audio and an I2C or SPI compatible
interface for control. The stereo DAC path features an SNR of 88 dB with an 18-bit 48 kHz input. In SE
mode the headphone amplifier delivers at least 33 mWRMS to a 32Ω single-ended stereo load with less
than 1% distortion (THD+N) when A_VDD = 3.3V. The mono earpiece amplifier delivers at least 115
mWRMS to a 32Ω bridged-tied load with less than 1% distortion (THD+N) when A_VDD = 3.3V. The mono
speaker amplifier delivers up to 600 mW into an 8
Ω load with less than 1% distortion when LS_VDD = 3.3V
and up to 1.3W when LS_VDD = 5.0V. The LM4935 also contains a general purpose SAR ADC for
housekeeping duties such as battery and temperature monitoring. This can also be used for analog
volume control of the output stages and can trigger interrupt events.
The LM4935 employs advanced techniques to reduce power consumption, to reduce controller overhead
to speed development time and to eliminate click and pop. Boomer audio power amplifiers were designed
specifically to provide high quality output power with a minimal amount of external components. It is
therefore ideally suited for mobile phone and other low voltage applications where minimal power
consumption, PCB area and cost are primary requirements.
