LM4930 September 2004 Audio LM4930Audio Subsystem with Stereo Headphone & Mono Subsystem Speaker AmplifiersGeneral Description Key Specifications The LM4930 is an integrated audio subsystem that supports j P at AV = 5.0V, 8 LS OUT DD voice and digital audio functions. The LM4930 includes ahigh quality I2S input stereo DAC, a voice band codec, a 1% THD+N 1W (typ) stereo headphone amplifier and a high-power mono speaker j P at AV = 3.0V, 8 LS OUT DD amplifier. It is primarily designed for demanding applications 1% THD+N 330mW (typ) with in mobile phones and other portable devices. j P at AV = 3.0V, 32 H/P OUT DD The LM4930 features an I2S serial interface for full range 0.5% THD+N 25mW (typ) audio, a 16-bit PCM bi-directional serial interface for the Stereo voice band codec and an two-wire interface for control. The j Supply voltage range full range music path features an SNR of 86dB with a 16-bit DV (Note 8) 2.6V to 4.5V DD 48kHz input. The stereo DAC can also be used while the AV (Note 8) 2.6V to 5.5V voice codec is in use. The headphone amplifier delivers DD 25mW to a 32 single-ended stereo load with less than j Total shutdown current 2µA (typ) RMS
