Additional preview pages of the LM4921 datasheet.

The LM4921 combines a 16-bit resolution stereo I S input digital-to-analog converter (DAC) with a stereo headphone audio power amplifier.

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. Boomer audio power amplifiers were designed specifically to provide high quality output power with a m.
