Product details

Description

The LM49352 is a high performance mixed signal audio subsystem.

The LM49352 includes a high quality stereo DAC, a high quality stereo ADC, a stereo headphone amplifier, which supports True Ground operation, a low EMI Class D loudspeaker amplifier, and an earpiece speaker amplifier.

Features

dual bi-directional I2S or PCM audio interfaces and an I2C compatible interface for control. The stereo DAC path features an SNR of 103dB with 24-bit 48 kHz input. The headphone amplifier delivers 65mWRMS (typ) to a 32Ω single-ended stereo load with less than 1% distortion (THD+N) when HP_VDD = 2.8V. The loudspeaker amplifier delivers up to 970mW into an 8Ω load with less than 1% distortion when LS_VDD = 4.2V. The LM49352 employs advanced techniques to extend battery life, to reduce controller o.
