Description

The LM49321 is an integrated audio sub-system designed for mono voice, stereo music cell phones connecting to base band processors with mono differential analog voice paths. Operating on a 3.3V supply, it combines a mono speaker amplifier delivering 520mW into an 8Ω load, a stereo headphone amplifier delivering 36mW per channel into a 32Ω load, and a mono earpiece amplifier delivering 55mW into a 32Ω load. The headphone amplifier can be configured for output capacitor-less (OCL) or single-ended (SE) mode. It integrates the audio amplifiers, volume control, mixer, and power management control all into a single package. In addition, the LM49321 routes and mixes the single-ended stereo and differential mono inputs into multiple distinct output modes. The LM49321 features an I 2S serial interface for full range audio and an I 2C or SPI compatible interface for control. The full range music path features an SNR of 85dB with up to 192kHz playback.

Boomer audio power amplifiers are designed specifically to provide high quality output power with a minimal amount of external components.

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
LM49321RL	CMOS7	0	16561	0	0	954000	4	270700104
LM49321RLX	CMOS7	0	16561	0	0	954000	4	270700104

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
