1 / 22 page  LM4893 1.1 Watt Audio Power Amplifier General Description The LM4893 is an audio power amplifier primarily designed for demanding applications in mobile phones and other por- table communication device applications. It is capable of delivering 1.1 watt of continuous average power to an 8 Ω BTL load with less than 1% distortion (THD+N) from a 5V DC power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The LM4893 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for lower-power portable applications where minimal space and power consumption are primary require- ments. The LM4893 features a low-power consumption global shut- down mode, which is achieved by driving the shutdown pin with logic low. Additionally, the LM4893 features an internal thermal shutdown protection mechanism. The LM4893 contains advanced pop & click circuitry which eliminates noises which would otherwise occur during turn-on and turn-off transitions. The LM4893 is unity-gain stable and can be configured by external gain-setting resistors.
