Product Summary

The LM4910MAX is an audio power amplifier primarily designed for headphone applications in portable device applications. It is capable of delivering 35mW of continuous average power to a 32Ω load with less than 1% distortion (THD+N) from a 3.3VDC power supply. The LM4910MAX utilizes a new circuit topology that eliminates output coupling capacitors and half-supply bypass capacitors (patent pending). The LM4910MAX contains advanced pop & click circuitry which eliminates noises caused by transients that would otherwise occur during turn-on and turn-off. Applications are (1)Mobile Phones; (2)PDAs; (3)Portable eletronics devices; (4)Portable MP3 players.
