More Information

The LM4921 combines a 16-bit resolution stereo I2S input digital-to-analog converter (DAC) with a stereo headphone audio power amplifier. It is primarily designed for demanding applications in mobile phones and other portable communication device applications. The LM4921 features an I2S serial interface for the digital audio information and a 16-bit SPI serial interface for internal register control and communication. With AVDD and DVDD = 3.0VDC and driving a 32Ω single-ended load to a 26mWRMS output level the distortion (THD+N) of the LM4921 will be less than 0.5%. The LM4921 also features a programmable 32-step digital volume control accessed through an SPI interface.
