LM4921 Datasheet Low Voltage I2s 16-bit Stereo Dac

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4921 Low Voltage I2S 16-Bit Stereo DAC with Stereo Headphone Power Amplifiers and Volume Control November 2004 LM4921 Low Voltage I2S 16-Bit Stereo DAC with Stereo Headphone Power Amplifiers and Volume.

General Description

The LM4921 combines a 16-bit resolution stereo I S 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.

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