The LM4921ITL from Texas Instruments is a 16-bit stereo digital-to-analog converter (DAC) integrated with a stereo headphone audio power amplifier. It is primarily designed for demanding applications in mobile phones and other portable communication devices.
This component features an I²S serial interface for digital audio data and a 16-bit SPI serial interface for internal register control. It offers a programmable 32-step digital volume control with 1.5 dB increments. The amplifier can deliver up to 50mW per channel into a 32Ω load with low distortion.
The LM4921ITL operates with a digital supply voltage range of 2.6V to 5.0V DC and an analog supply voltage range of 2.6V to 5.5V DC. It also includes zero-crossing detection for silent attenuation steps. The device is available in a compact 20-bump DSBGA package, suitable for space-constrained designs.
Key specifications include a 16-bit resolution, a PSRR of 52dB at 217Hz, and a low shutdown current of 1µA typical. The operating temperature range is -40°C to 85°C.
