Operating on a 3.3V supply, it combines a stereo speaker amplifier delivering 520mW per channel into an 8Ω load, a stereo headphone amplifier delivering 36mW per channel into a 32Ω load, a mono earpiece amplifier delivering 55mW into a 32Ω load, and a line output for an external powered handsfree speaker. It integrates the audio amplifiers, volume control, mixer, power management control, and Texas Instruments 3D enhancement all into a single package. In addition, the LM4934 routes and mixes the stereo and mono inputs into multiple distinct output modes. The LM4934 features an I2S serial interface for full range audio and an I2C/SPI compatible interface for control. 1 23 • • • • • 18-bit Stereo DAC Multiple Distinct Output Modes Stereo Speaker Amplifier Stereo Headphone Amplifier Mono Earpiece Amplifier Mono Line Output for External Handsfree Carkit Independent Left, Right, Headphone and Mono Speaker Volume Controls Texas Instruments 3D Enhancement with Programmable Effect Level I2C/SPI (Selectable) Compatible Interface Ultra Low Shutdown Current Click and Pop Suppression Circuit APPLICATIONS • • Boomer audio power amplifiers are designed specifically to provide high quality output power with a minimal amount of external components.

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX ,θJA, and the ambient temperature, TA. The maximum allowable power dissipation is PDMAX = (TJMAX – TA) / θ JA or the number given in Absolute Maximum Ratings, whichever is lower.
